You'll have to use dial-up service, but it works pretty well. $0.35 per session for the phone call...not bad. I use Earthlink and it is a fairly fast connection.
Just be careful and make sure the number you call is local. In that area you must dial the area code on local numbers. Some 407 numbers dialed (without dialing 1) wll be local but long distance. Check up front to make sure the number you're calling is truly local, the operator at the resort should be able to tell you or find out.
