If you have had/been to a birthday party at an amusement park (going to be 7) - how long was it for?

Right now the party starts at 12:30 and they do not have a time set that it is over, they said the kids can run the park all day if the parents wanted to stay.. KWIM?

I am thinking of putting the time from either 12:30-3 or 12:30-4

Which would you pick? Thanks Chat Icon
