I was there the first week of June and it was fine with Verizon. Friday afternoon it started buffering. 3am Saturday morning it was great. After sunup Saturday it was unusable. I assume it's just the result of a massive weekend population growth in a tourist attraction town.

As other's pointed out, it was poor on Saturday all day for me.

Verizon had about 2 bars if I recall correctly. It depends how far away from the highway you go.
