Kenny the pirate just posted on Twitter .. saying that you can only have 2 g+ selections at a time now. I'm hoping people that are there right now can verify. So one g+ than if you hit the 120 rule u can have one more. Than you must use one before you can get the next g+.
Makes sense. Seems the original intent was to only let you pick a Genie selection every 2 hours. Disney is just closing the loopholes for those trying to 'game' the system.
