Hotel Reservations:  The MTC has secured a block of guestrooms at a rate of $201.00 plus tax. To ensure you get our negotiated rate, reservations should be made online using the following link, Sonesta Denver Downtown Reservations or by dialing (720) 269-3256 and stating that you are booking a room for the MTC 2024 Annual Meetings.  The MTC rate will be available until our cut-off date of Monday, July 8, 2024, or until our room-block is sold-out—whichever comes first. Based on availability negotiated rate will be available two-days pre, and two-days post our event. Reservations after cut-off date will be accepted based on availability at the negotiated group rate. Rates are subject to a $20 per person, per night, room charge for any additional guests. Reservations after cut-off date will be accepted based on availability at the negotiated group rate.

Individual reservations can be cancelled at no charge 72 hours prior to scheduled arrival. Any cancellations after this time will be charged one night’s room & tax.  If reservations are part of a rooming list, same policy applies.

Early Departure Fees

In the event a guest who has requested a room within your block checks out prior to their reserved checkout date, the hotel will add an early departure fee in the amount equal to one night room and tax to that guest’s individual account. Guests wishing to avoid an early departure fee should advise Sonesta Hotel Denver downtown at or before check-in of any change in planned length of stay.
