Tickets start at $40 and go as high as $300 if I'm not mistaken. You can get good endzone seats (Sec 123) for around $70. When I went last December I bought my ticket at the stadium, the Saturday before the game. With Ticketmaster you can print them at home but don't use that, you'll be extra for the fees. You can also arrange to pick them up on the day itself but I have no idea how that works. I don't think there are stadium tours but can always email the ticket office and ask.

 

Since you're on your honeymoon here's a few extra tips: Fly in on Friday, buy tickets on Saturday, game on Sunday, leave to do the rest of your honeymoon on Monday. Stay near the beaches, downtown Jacksonville isn't much fun. If you want to buy merchandise, do so at the Avenues mall. If you get carded buying alcohol, use your drivers license instead of your passport, guaranteed odd reactions.
