This and, obviously the highest thrill slides which are also the ones inside the Volcano are mostly 1 person at a time slides. These are going to command quite the wait for the foreseeable future. Now, if you're telling me the only way I can ride these is Tapu Tapu the "no line system", then great! I love not waiting in line... but if you are also telling me that for that 4-5 hour wait all I can really do is eat food and float in the lazy river... no thanks!
I think the system sounds great, especially when the park would never have the capacity to hold 6 hours worth of line for a single ride... but you aren't really spreading out your people if everyone is waiting for 3 slides and doing nothing else because the rest of the slides are on a 30 minute wait, and you aren't allowed to so much as look at them until you've gone through your 5 hour wait.
I'm glad you got me out of line, but now you gotta give me more flexibility with what I do during that 5 hours.
Now if these slides eventually average out at say, 30-60 minutes then sure, not that big of a deal, but if they average at 2 hours plus... I am not going to be happy floating around that long.
I guess my fear is, obviously no one wants to wait in a 3 hour long line, so obviously you're going to think, "Geeze, 3 hours already?! I better get my wait started", now the entire park is all waiting on 3 slides and doing nothing else but cramming the river, and spending money on food...
Oh, I guess that's kind of brilliant on Universals part....
