how long roughly is the tour

1 to 4 hours, you go your own pase through the museum after the first 30 min of a guided tour

I spent about 2 hours in the museum but you can go pretty much as fast as you want to go but there's a lot to see and of course at the end you get to drink all the soda do you want from all the different countries and of course North America was my favorite but I did like a few of the flavors from other countries
