My day in ZG15

ZG15 is an "extreme sporting event" that took place in Panama from january 7th to january 11th in which you could've pay could have paid the incredibly cheap price of ten dollars to buy a ticket that would have allowed allow you to get access to all the amazing activities that ZG15 offered (rappelling, paintball, climbing, go carts and many others) and experience the most exciting adventure ever.

That's what the commercial showed and said, but what appeared to be entertaining on tv was quite different in real practice.

My brother, sister-in-law and I went to the event at Sunday 11th ready to hop into all the exciting activities, so we bought three tickets and got in with no problem. once we were in we rigidly stood for thirty seconds or so taking time to understand what we were seeing, just six different activities, each one with lines of hundreds of people long and only two activities looked attractive.So then for another thirty seconds we were just thinking. I don't know what the two of them were thinking, but I myself was pondering about those ten dollars I would never see again.

we tried to enjoy the limited options that we had, but during two and a half hours we were barely able to do two lazyboring activities. Finally we had to choose between making line along with a hundred people to play paintball or return home. So we all decided to return home with ten dollars less each.

Note: could you tell me what other word could I use instead of activity in this usage? I'll wait for corrections.

I think activity is the best word to use . If I were speaking informally, I might say "We saw that there were just six things to do."
