I have gone to a good majority of the games so far and plan to continue to. I'm not a season ticket holder, but since I'm a student I can get in free. I know that the Tuesday games are usually $1 nights so general admission tickets are $1 and you can get soda, water, hot dogs, and popcorn for $1 each.
On a normal night general admission is $4.
Believe me, it is definitely worth it. There is nothing like sitting out at a ballgame when the weather is nice and watching the Gators play. I recommend you try and make it out to a few games.
