I think the FITS are great, but.... the only thing that finally made me duck out of getting them was that whole "expiration" thing. Once that pass gets "activated" -- it has a set lifespan of 30 days. I'm always too spooked by the idea that something will happen (like a child gets ill, forcing both child plus one adult to be miserable in the room, while the clock ticks on the pass...) I was sooooooo close to getting these for our 2-week trip, but we're taking family with us, and their son has laready had many medical issues this year... if they canceled, their tickey would still expire in a year. And if they came and something happened on vacation, just extra worries on top of worries if the passes are also expiring.
So alas... just ordered 7 day PHP's from HWSC for 302.90 per adult...I'll chalk up the cost of my b'fast and kids' DQ trip as my "insurance" fee to have a ticket that, if for any reason unused, won't expire. Just call me chicken liver....
