You could do that but If I may make a suggestion, If you stay at the Country Inn Suites or the Residence Inn,(Theres another brand new hotel across the street which I cant speak for since it opened within the last few months) which are literally next door to each other, there is a Hertz car rental in between the 2. After you have dinner, return the car and you can walk back to either of the 2 resorts, and then take the resort bus from CIS or Residence Inn, next morning. CIS I know takes bus reservations so when you check in, (you can call 24 hours in advance) you can say I want the say 11am bus. You walk down to conference room by 1030ish, (They also have a comp breakfast for the cruise package) and the drivers will be there to walk you to the bus. They also have luggage carts to put your bags on, so all you have to do is pull the cart with your bags and have a seat. The drivers will load the bags and unload them at the port for you. Both busses drop you off same place a car would drop you off, and there are porters on the curb to take your luggage.
