yes, when you are done with the tour at 11:00, you are free to do the park any way you wish.
you could do stay and scream and do about an hour before your tour begins.
you could catch a couple of houses in advance if you get out of the holding area at 5:30ish.
saturdays have more crowds. it is a great way to do hhn on a saturday.
you'll have more access to the houses and avoid the long lines while you are in the tour.
hopefully you won't get caught up in long lines for any of the shows or repeating houses.
the last time i did the non private tour of 5 hours, it included bill and ted and the houses.
i assume the 4 hour tour will cover the houses and bill and ted also.
you could be walking through some of the scare zones on your tour.
i like the private tours as you can request the agenda for your group that night.
you also will only have people you chose to be in your group.
one year i did the private tour and 6 homies signed up for the same one so we could be altogether.
some of the others in the group were a real downer.
they didn't want to do the houses, they wanted to do rides or just sit and look around i guess. we did have 2 other couples that went with the flow on doing the houses and shows.
six of us knew each other from the boards, the others we didn't know.
you were put in groups up to 20 that year. if i remember correctly, we had 15-6 in our group.
now, it is more limited to the number of peeps in each group.
it was after that tour, i decided to book the exclusive/private ones for future tours.
no matter which tour you take, the RIP tours will spoil you.
you will thoroughly enjoy it!
