I am getting ready to rent my Marriott unit for the first time and have combined together a few that contracts that I like and have a few questions for those experienced renters. How do I know my unit # to put on the contract when it is a floating unit and how do I know whether or not it is smoking or not? (the reservation said non smoking cannot be guaranteed). Also, what do I give them as confirmation that it has been reserved and the unit put in their name? Also, I am renting Presidents week for next year, so when should I start advertising? I was thinking of waiting until 7-8 months ahead of time and asking for 100 % up front. If I advertise now, I feel that it might be a negative in renting it buy asking for 100% so early. Any thoughts? thanks!
