We're planning a 7 -day visit to the Keys the week between Christmas and New Years. We normally like to stay in a single spot (apartment or condo rather than a hotel room) rather than move around and assume that one can do "day trips" relatively easily from one place. Can you recommend a location which would suit this purpose and ways to find such accomodations? Are rental agencies the way to go? Or is it best to go to different locations for a few nights each? Also, what is the weather likely to be? Thanks for any suggestions.
