I was recently at Boardwalk very close to Dolphin, and I found a cell phone tower repeater on top of Jellyrolls (at least the part that faces Boardwalk.) On my balcony I had excellent 100+ mbps speeds on AT&T. A family member trying inside the room had much higher latency and the screen stalled when trying to join.Staying at the Dolphin in October. What's the Wifi situation like at those 2 hotels? Is it the standard Disney fare? Have been trying to figure out if I'll go wifi or not.
So if you have a weak signal inside, walk a little toward Jellyrolls on the boardwalk.
