Check Tropical Palms in Kissimmee f0or your Universal part of the trip. In the keys, since you want to take the ferry over to the Dry Tortugas, staying close to Key West is advisable as it's a long day trip on the boat. Boyd's is close by and you can take public transportation to the docks or it's an easy bicycle ride if you have bikes. Call them as soon as you figure out your dates.... I had to change a reservation there yesterday and they were able to accommodate me , so they must have some open slots right now.
