Policies & General Info


Check-in is between 4:00 pm and 8:00 pm. Please call as soon as possible to inquire about early check-in and late check-out as we do our best to accommodate requests. Check-out is 11:00 am. 


Transient Occupancy Tax of 8.5% is charged on the room rate only. The Tourism Business Improvement District tax of 3% is also charged, per day.


To guarantee your reservation, we require a deposit equal to the first night’s charge, plus tax, at time of booking. If the credit card is declined, we reserve the right to cancel the reservation without notice. Up to $200 per room/per stay deposit will be authorized at check-in and will be removed after check-out following assessment of the guestroom, if no damage or disturbance occurs. If damage or disturbances occur or additional deep cleaning is required, the deposit will be forfeited by the guest and additional charges may be incurred.


Please note that there is a two-day cancellation policy and any cancellation should be made by 2 pm two days prior to arrival to receive a full refund of your initial deposit. If your reservation is cancelled within 48 hours of your arrival, then you will forfeit the initial one night deposit charge, including taxes. 

Reservations made within 48 hours of the arrival date are considered non-refundable. Guests who fail to cancel their reservation and do not check-in on the day of arrival will forfeit their entire deposit and the remainder of the reservation will be cancelled. Guests must contact the inn directly over the telephone to cancel a reservation. A cancellation cannot be made via email, fax or voicemail. Please ensure to make note of the cancellation number.


Guests are required to present a valid (government-issued) photo identification at check-in that matches the name on the reservation as well as the credit card used to pay for the guestroom charges.


We require a valid credit card on file to guarantee your reservation. Depending on your booking rate and channel, your card may be charged for your stay in advance. If you are pre-charged, your original credit card used and the valid credit card holder must be presented upon arrival. The applicable policy will be referenced when booking as well as noted on your confirmation. 


On the morning of your arrival, your card will also be pre-authorized for $50 for incidentals. Upon check-out, if there are no additional charges, our system will notify your bank that we have released this pre-authorization.


Guests with a confirmed reservation understand and agree to be financially responsible, subject to the noted cancellation policy, for the entire length of stay reserved, including all incidentals charged and any property damage due to guest negligence.


If you choose to use a debit card to guarantee and pay for your stay, your bank will automatically hold additional funds, beyond the expected amount due, in an effort to cover any incidental charges. We have no control over the amount your bank will hold or when the funds will be released back to your account. Please check with your bank for further information


If you wish to pay with cash, you may do so upon arrival, however, a credit card pre-authorization of $50 is required for incidentals. We apologize for any inconvenience but we do not accept checks. 


If you are paying for another guest’s stay and not staying at the hotel, you will be required to submit a credit card authorization form with identification and signature; your card will be charged at the time of reservation for the entire amount


Groups requiring three or more rooms at a time are considered a Group Reservation. Group reservations cannot be made online. Reservations that are made with a group booking are subject to a longer cancellation policy and require a non-refundable deposit. This will be stated on your confirmation. If you have any questions, please contact the manager about your cancellation policy. Guests who fail to cancel their reservation and reserved their guestroom through a third party site are subject to a no-show charge equal to the entire stay.


Diablo Mountain Inn is 100% smoke-free. Please do not smoke in any of the guestrooms or within 25 feet of the building (including vapor cigarettes). If smoking occurs, there will be a minimum $200 cleaning fee per night added to your folio. Please know we strictly enforce this policy.


Diablo Mountain Inn has a few dog-friendly guestrooms. If you are interested in bringing your dog, advance reservations as well as a nightly fee is required. Please click here for additional information. Guests who bring a dog to the hotel without making an advance reservation or notifying the staff will be subject to a $200 charge. Please know we strictly enforce this policy. If you are interested in bringing your pet, please call the hotel directly to review the policy and inquire if the pet-friendly guestroom is available during your dates of stay.


Room rates are based on double occupancy. If there is an additional guest (over the age of eleven) staying in the room, there will be a $10 extra person nightly charge. Unfortunately, we are unable to supply rollaway beds or cots.


We welcome families and children. For your comfort, please speak with the innkeeper directly to determine the best room to accommodate your family. Quiet hours must be observed for the comfort of all in the hotel. Children, ages eleven and under, stay free. Travel cribs are available for an additional $10 per stay fee and must be requested prior to check-in (we cannot guarantee availability).


Guests who need to check-out earlier than expected from the hotel should notify the front desk by 6:00 pm, two days before departure. Guests who booked through an OTA will not be refunded. Guests who book directly can tell us by 11 am on the day they wish to leave and get a refund (after any discount for an extended stay is removed) for the days not used.


Burning candles and incense is not allowed due to the potential fire hazard. Please do not light anything in your guestroom. If flames or smoke of any kind are detected, you will be liable for the entire amount of damage.


Our hotel has been inspected by a California Certified Access Specialist and has one ADA-accessible guestroom and one hearing impaired guestroom. Please click here for more information.
