When I was stationed in Pensacola me and a few friends made the quick trek to J-Ville for a Bills game. It was a fantastic experience. We stayed at the Omni at the Landing. The Landing is on the St Johns River and has plenty to do- Bars, restaurants, etc etc.
There was a water taxi that comes to the Landing and takes fans right to the stadium. I dont know if thats an option now but it was super cool- drinks were allowed. Once at the stadium, there was a nice outside area that had beer/food and a band playing- again, alot of fun.
On a side note, at the Omni I met Paul McGuire, Joe Theisman, and Suzy Kolber- all were super nice!
Hope this helps- Go Bills!
