We rented a condo through Royal Shell Vacations website. We looked at several places on Sanibel and decided that this location would be best with our small children (11, 8, and 5). We wanted tranquil water and close to restaurants, etc.
We then chose from one of several at Loggerhead Cay. The one we rented was very nicely decorated. It was clean, had loads of whatever kitchen supply we might need, tons of bath towels, beach toys, movies, puzzles, books, etc. The beds were VERY comfortable! My son even liked the pull-out couch!
There is a short walk directly to the beach either via a boardwalk or a path. The grounds are nicely kept. Lots of flowers and bushes. The pool was clean and warm and close to our room. We had easy access to a tennis court if we wanted (we didn't!). The condo building itself is not as "pretty" as some of the newer ones (this one is 15 or 20 years old), but the inside of ours was totally redone and beautiful.
The people at Royal Shell were great. Booking was a breeze. We were able to check in early and found dish soap, dishwasher tablets, and garbage bags in abundance in the condo. The other nice thing is that the RS office is very close to the condo, so we got our keys and within 5 minutes were walking up the steps to our room.
I would definitely stay at Loggerhead Cay again and would definitely use Royal Shell Vacations again.
