We were planning to leave for a trip to Tulum, Mexico this week, but the Swine Flu is turning us back. Looking for something similar -- quiet, clear water, white sand beaches. Never been to Sanibel, but it seems like it might be just the thing. Can anyone recommend a quiet place to stay, on the water? doesn't need to be fancy, but clean and quaint. Our Tulum budget was $115/night. I know we can't expect that in Florida, but something affordable would be great.
