Few things to make G+ better:
- Pre-purchase G+ with a WDW vacation pack (like you used to be able to do) like hoppers
- Imagine having to buy hoppers the morning of based on park demand? lol
- X days prior to your vacation you can book 1 attractions via G+.
- Resort guests can book their 2nd G+ the day of at park open from anywhere. Everyone else has to book once they enter the park.
X has to been at least a week or so prior to check in because a day or two prior to check in is just one more hassle to organize on top of everything else people do right before they start vacation (packing, traveling, wrapping up work etc.)
They've offered 1 before.
They've offered 2 before with FP+.
They already do a version of 3 with ILLs and resort guests.
Would make the system better AND add more perks to staying on site.
