I have enough airmiles saved to purchase 9 day park hopper tickets for our upcoming trip. I also have enough to buy them with Genie +. Is it worth the extra airmiles for Genie +? Or is it better off paying as you go for Genie +? Also if I purchase base tickets instead, can park hopper be added at the parks? I'm not sure if we will park hop, but want to purchase the tickets soon.
