Just got back from a short 2 day trip. I stayed on site, so was able to purchase LLMP and book 7 days in advance. My flight was due to land at MCO at 8:50AM, and I had no idea how long it would take to get to my first park for that day, which was Animal Kingdom. I was taking Mears Connect and I knew from past experience that transfer times can vary widely. I booked my first LL for 11:30 and booked the other 2 for later times hoping that I would be able to modify to better times once I got there.
I lucked out and got to my resort by 10:00AM, gave my luggage to Bell Services and headed to the bus stop. There was an AK bus at the stop, so I was on my way to AK by 10:15ish. Had no trouble modifying my LL to 10:15, and modified my 2nd LL to 10:30. After tapping in to my first LL, I modified my 3rd LL to Haunted Mansion at MK for 3:30. I got my room ready text while at AK, so after Safari, Lion King and picking up my AP magnet, I headed back to my resort to rest a bit before going to MK.
I had a ticket to
MNSSHP, so I had 3 LL for 3:30-5PM. Arrived at MK about 4:10 and just used the regular day entrance to get in. The party entrance had a long line. I had HM, PP and Pooh LLs. I don't do roller coasters, so I don't know if there were times available for SM or BTMRR. Of course there was nothing available for Tiana, but I wasn't interested in that either (didn't want to risk getting wet). I tapped in to my 3rd MK LL at 5:04 and there was nothing else available to book after that. I did all 3 of my booked LLs between 4:30 and 5:04. I think I paid $16 for LLMP since I started at AK, so I was happy with the 5 LLs I got. If I had been willing to go MK earlier than 4, I'm sure I could have gotten several more LL.
My second day was at HS, and I was not interested in rope drop, because I was checking out of my hotel and wanted to have a relaxed morning. My flight out was for 8:10pm and Mears was picking me up at 4:40.
I had pre-booked LL for MMRR, Toy Story and Indiana Jones.
Was granted a late check out of 12:15, so I just kept modifying my LLs until my first one was for 12:20. I had no trouble modifying to slightly later times. Got to the park and tapped in to MMRR at around 12:45. After that, I booked a LL for Soarin' at Epcot, and then modified my other 2 LLs to Nemo and Spaceship Earth. I knew the wait times for those rides were short but booked LLs anyway, as I didn't want to only use LLMP for 1 ride. This day ended up being a waste of my money by purchasing LLMP.
I will say that this experience makes my feel a bit better about LLMP in that it seems to be easy to do day of modifying in order to get better times and even get rides that weren't available on sign up day.
However, going forward, if I do any more super short trips like this, I doubt seriously that I will purchase LLMP. It changed my focus and instead of being able to go with the flow and enjoy my day, my focus was on getting to the rides and booking another LL.
