I'm a take it or leave it kind of gal with FPs. I gave up searching for the perfect FPs for our MK day on December 23 about a week before we left for our trip. It was stressing me out too much! We had an ADR for dinner at CRT. We had never been to WDW that time of year before. Previously we've been late January/early February or late March/early April, so I was really anxious about the crowds. The only thing on our "must-do" list was 7DMT so we decided to just head there first thing and be prepared to wait in line. I used Touring Plans and came up with a plan that I thought would work out OK for us. On December 22, I did end up getting some FPs for Space Mountain (hubby's fave), Monsters Inc (a highlight from our last trip) and Under the Sea (new!) so I re-worked our TP keeping in mind that as long as DD got to do 7DMT, we used our FPs and we made our ADR, I would consider our day a success. DD wasn't into the Princess thing anymore so the M&G were not a priority at all for us. The FPs ended up working great for us and we even ended up getting another FP for Haunted Mansion (never done before), which I was really excited to get. We hit 7DMT first thing and the posted time was 45 minutes but it was actually more like 30 minutes (and felt even shorter than that). The rest of the day was great. We did a lot in FantasyLand in the morning (Mad Tea Party, Dumbo - those 2 are my faves - Small World - MIL's fave, Philharmagic - a sit down break my FIL with a sore back really appreciated). For some reason, we hit almost no lines for these attractions. Its like the crowds parted for us. We just simply lucked out. It was getting really busy though so we found a good spot for the parade (had lunch and ice cream while we waited), then our FPs for SM and MI were in the afternoon so we hung around Tomorrowland/Fantasy Land until it was time for Under the Sea and then it was time for dinner. Dinner was great and we got a good spot for the Castle Lighting. Hubby's parents then decided they had enough and left. By that time, I had scored our FPs for HM so we headed there and then found a spot for Wishes. By that time, we were pretty much done but walked around for a bit, couldn't agree what to do next so we left. Could we have done a lot more? Yes for sure. We didn't spend time anytime at all in AdventureLand or FrontierLand but we've been before and there was nothing there we REALLY wanted to do. Did our FPs help? For sure, but I don't think it would have ruined our day if we didn't have them. We would have waited in line for Space Mountain and missed Small World if we had to. We just went in with the "We are at Disney at Christmas - this is awesome!" attitude and had a great time!
