Of all the places we've been in the Caribbean, Aruba is our least favorite and probably won't go back. We do have fun memories of the party bus or booze bus as it is sometimes called.
We went on one trip to Turks and Caicos and one trip to Aruba. Since then 10 trips to TCI and none to Aruba. Although we liked Aruba, it was too built up and crowded for us.
Anguilla is on our bucket list. I hear their beaches are comparable to Grace Bay.
Nothing wrong with Florida, we've done plenty of fun trips there without breaking the bank.
