With all due respect, that's more of poor planning on your part than a failure in the system on Disney's. Fastpass it. We've got all our Fastpasses booked for July, Space Mountain obviously being one of them. There's a way to properly use Fastpass+ where you can avoid the lines for the most popular attractions. And at least you have other options in the meantime. I've never waited more than 30 minutes for a ride at Disney. Before or after Fastpass+, and I hit everything I want to during the day. If I was told "Sorry, you can't ride Pirates of the Caribbean" for 4 hours until you ride Space Mountain, I'd be furious.
I'm sorry I didn't know I was going to Disney until the morning of the visit. Disney's system requires more planning and has its pros AND CONS. If you don't plan in advance and they're busy, you're stuck spending even more of your day in lines. Unable to do anything else while in lines.
I've also had the experience at Disney where the ride had delays while I was waiting on line, and I had to go to the bathroom, and I had the choice of leaving the line to go to the bathroom and losing my spot or suffering to hold it in. Tapu Tapu solves that problem. Also, Tapu Tapu DOES allow you to leave one line and enter another, just like Disney's standby lines do. You are not forced to stay in a line if you decide its too long after entering it.
Secondly, they may be loading as fast as ops can load them, but not as fast as they can be loaded. That's been very well documented. That however, is fixable.
That also has nothing at all to do with Tapu Tapu.
Having standby lines would divide however many people are in the park at one time up by 18 different attractions.
So are you saying the issue that there are too many people lounging on the chairs around the pools and in the pools and non-queued attractions? I haven't heard that complaint, but that would be the most valid one about Tapu Tapu.
Instead of waiting 4 hours before doing anything, you could hit 4 or 5 slides (at the minimum) in the interim.
Tapu Tapu does permit you to choose which ride you ride, and you can choose the smallest wait time ride each time.
This is a water park. It's not some new concept that has never been attempted before. There are thousands of water parks in the world, all which get crowded during the summer. Typhoon Lagoon is the most visited water park in the world, with fewer attractions than Volcano Bay, yet people (myself included) spend a day there and manage to do see everything. If Disney can operate a water park with more people and fewer attractions successfully, why can't Universal?
I'm curious if any opening day and opening weekend numbers were released? And how that compares to a peak Typhoon Lagoon day, with number of people and wait times?
From what I can tell, you don't have any complaints with Tapu Tapu, just how crowded the park is and perhaps the speed of the ride ops
