Calling it overpriced is not a correct use of the term. Saying you don't see value at that price is more appropriate. I have a hunch these tours could sell out. Which could mean they are under-priced.
I'll take that bet.
People are stupid about Star Wars, so they can pretty much price that whatever they please and people will pay it.
Avatar as the main draw? Nah.
Especially with this recurring frequency - this is going to be one of those failures that quietly gets shuttered. Probably changed to fewer offering days at first, until it just disappears.
A family of 4 is going to spend nearly $1100
plus park admission for four hours in AK with absolutely nothing unique or special. I have a hard time believing that people that could afford that would be willing to spend that kind of dough - because if they are the types that wasted their money like that, they wouldn't be able to afford it in the first place.
Even those with "limited time" - in that case, you are talking over $1500 since you'd have to buy tickets anyway. There are not enough people on earth who care about Avatar that much to make that work, much less enough wealthy people that will be duped into it. If time is so limited, anyone who isn't ridiculously wealthy, without severe cognition issues, is going to say "well, that's half the price of a Disney vacation to begin with, let's just go when we have more time".
Again, I hate to say it - they could get away with this with Star Wars. There are swaths of people out there who abhor WDW and Disney in general who will be compelled to come, and I could see them just paying through the nose to see exactly what they want to see and leave. But when Avatar is the central theme? This isn't going to last long. If you've got this kind of money to throw down, you are likely the type who can just afford a guided personal VIP tour to begin with.
