I was planning a trip to Key West for the family early next year (using Marriott points) and was looking at the Key West Marriott Beachside hotel. While I haven't stayed there yet, I did find out it was originally built to be an MVCI property (a Marriott Timeshare). So it has lots of 1, 2 and even 3 bedroom suites and they all have full kitchens. Not sure if they have balconies or porches, but you might give them a call and ask. I've stayed at a number of other MVCI properties (Hawaii, Florida, St. Kitts, etc.) and they are all very nice.
