The State Travel Office does not enter into contracts with any hotel properties.
PPM 49 does not mandate specific hotel properties where a traveler must stay. PPM 49 only states the maximum dollar allowance a traveler can be reimbursed for lodging.
The State Travel Guide references a number of hotels that will offer a limited number of rooms at state rates. However, since there is no contractual agreement, these hotels do not guarantee their rate for last room availability. If the hotel property has a large occupancy for your date of travel, then your chance of obtaining a state rate decreases.
The important thing to note when making travel arrangements is to seek hotel reservations as early as possible. That will increase the opportunities to find a rate at or below state contract. Be sure and write down the reservation number as well as their cancellation policy. If travel plans have to be changed or cancelled, then you must cancel your reservation within the allowable time frame.
