We go about once every 2 years. Have not experienced any of Galaxy's Edge yet. That is kind of the main event of this trip, but we also want to experience the other three parks. Park days are 12/27-12/30, four days. Originally when I purchased our tickets, the only HS day available was 12/27, so I booked the four days in this order: HS, AK, EP, MK. Now I see that every day of our four has all four parks availalbe (at least right at this moment). Shoud I book a back-up date in HS (for example our AK day), in case I don't get a ROTR boarding group at 7am for our planned day? If I do that, will I be able to get a park pass for AK last minute? Can you book a same day park pass? Any chance that AK would fill up? Any advice is appreciated? TIA!
