If you are explaining the past afternoon, you would use 'were'. If you are explaining it while you are there, you would use 'are'.

People is plural so there is no need for the "s" at the end.

I would change "as much as possible" to "a lot of" in this sentence to make it sound more natural. "As much as possible" in this sentence makes it sound like you were trying to have fun despite not enjoying the activity.

"Survive" would be better replaced in this sentence. "Survive several times" also doesn't really make sense as "survive" is a one-off action until it is no longer applicable.
