We typically stay at the Marriott Resort on Hutchinson Island, but they were sold out this weekend so we stayed at the Courtyard just 4 miles North.
Rooms are small but comfortable and nicely furnished. The in-room coffee is terrible so coffee connoisseurs beware. There is a restaurant with netter coffee, but breakfast is not included in your stay.
The pool is quite small but it is adjacent to the beach so probably my not an issue.
FYI, not all rooms have balconies - make sure you specify if you want one.
