I have been monitoring Genie+ return times and this system is in for a real test in 2 weeks during Thanksgiving break.........
As of right now, it looks like Hollywood Studios will be a disaster since most of the rides will "sell out" by park opening.............My guess is SDD, MFSR, ToT and RnR will all be sold out before you get a chance to book your second Genie+ (unless you get an early window on your first)
If you book SDD, its almost a foregone conclusion that you will not get MFSR, ToT or RnR.......That leaves Star Tours and TSMM as the only 2 other worthy options
This doesn't even take into account that ROTR and MMRR will likely be sold out by park opening
I guess all i can say is, BUY DIS STOCK!
