These will be insanely popular. Let's take a family of four staying Club at the Poly for a week after Easter (crowded) They are paying roughly $8000 for that with taxes etc
To add this on will be $200 a day times six park days....$1200. It will be a no-brainer for many guests.
For certain times of the year, I absolutely agree. 3 extra fastpasses would be a bit of a miracle on days like New Years Eve when the MK hit capacity, not even to mention the special seating area. I certainly hope Disney gouges those people as much as possible on these special dates. On top of the $50 extra for fastpasses, club level rooms should cost $1500+ to book on especially busy dates.
On a date like April 14th or something else random like that, there is almost no way where this service is worth the extra cost.
I, too, am upset with the 90 day window. Giving people something extra for an extra cost is fine in my mind, but allowing them to bump me in line just because they are spending a little extra money makes me feel unappreciated by Disney. Hopefully more people steer clear of the parks due to not getting the fastpasses that they want and it will force Disney to change this area of the deal.
