Colosseum Arena Only Ticket question

We did the Colosseum with 24-hour Arena Floor tickets on May 19. We also booked tickets for Tiers 1 & 2 immediately after our Arena Floor time frame. No one was paying any attention to how long we were on the arena floor. Once we were in, we could have stayed for an hour (though 20 minutes is sufficient to see what you want to see there). When we exited, we ended up getting funneled up to to Tier 1 and through there to the exit. (you enter and exit in completely different spots). So while we did go back in with our Tier 1 & 2 ticket, and my husband very much enjoyed the views from Tier 2, I felt the arena floor was sufficient. I will say that it's VERY confusing how to exit and were to go, signage is poor and they have roped off areas on the way to the exit with people monitoring to keep folks from backtracking, apparently. Also, once you're up to Tier 1, they don't want to let you backtrack down to the basement to use the bathroom, although we talked our way down there. They want you to exit and use the restrooms outside because the ones inside get very, very crowded (this was our experience). Lastly, the arena floor entrance area is separate from either the individual or group entrances, and it's completely around the other side of the Colosseum. As you're facing the Colosseum at either the individual or group entrances, walk left allllll the way around the Colosseum. Right before the fencing begins you'll see a white tent-top; that's your entrance. There's a restroom right over on that side, too, that not many people know about; quite convenient.

Thank you sooo much. This is very informative!
