OP, maybe it depends on your location. Every time I used the iPad, I was on the balcony overlooking the Boardwalk or in my room (near the door to the balcony). It could be that there are some dead spots in other parts of the resort but we had no issues. The previous year, in the same location, the internet was slow and would kick me off after a few minutes when logged on. This past October was great.
