I'm sure it depends on the resort and where your room is located.
We were at All Star Sports in Jan. 2015...
worst WiFi I have ever experienced in a resort!
It was simply unusable during evening hours.
When we got up at 6:30AM to head for AM EMH, the WiFi would connect and run OK.
But, when lots of other guests were awake and using the wireless...
it was USELESS!
