I'm intrigued to know how logistics would work if some people were riding Avalanche and others were not.
I'm not really interested in Avalanche ERT in all honesty. I'm potentially interested in the Icon ERT, although I think £25 for 30 minutes is massively overpriced, especially if it's before park opening when the ride isn't at its best, and given how easy it is to get re-rides during the day. The originally suggested ballpark price of £15 was a lot more reasonable. I may still be up for it, but it'll depend on how things work out - if we had Icon rides stupidly early, and then some people go off to ride Avalanche for an hour before the park opens properly, I can't imagine faffing around in the interim being a fun experience. I might consider adding on Avalanche, but only if the park has some means of accommodating those of us who already bought wristbands.
If the Icon ERT is around the 30-45 minutes before park opening, or is immediately after the ride closes to the general public, then yeah, put me down. If the arrangement are different, I'll have to think very carefully about dropping that amount of money.
Whatever happens, any ERT will have to be at the up-charge price for me - I've already got my wristband for the day, so I won't be getting a bundle price that includes one.
