Does it count when the longer trip is part onsite and part off? We also did Universal that trip:
Day1 -arrival day-CBR check in-head out for dinner and trip to store (had car-flew into Sanford) to stock room with breakfast and snacks, drinks at resort bar (kids were tired so DH and I got some couple time to talk)
Day2-Early am MK (BOG lunch) break at resort, back out to DHS for FP and dinner (we went during SWW so lot of Star wars stuff)
Day 3- am EMH at AK -done by noon so headed to AKL for Sanaa lunch, then break at resort,pm was MK night and the fireworks and FP+
Day 4- resort change day-sleep late, laundry by quiet pool, check out and off to BC-where room was ready! So settled in and headed to EPCOT for FP and dinner. Early night and we headed to resort for nightcap at HH
Day 5-open to close DHS for SWW -Galactic breakfast at Sci Fi, dinner at 50's Prime Time (3 of us did have a resort break)
Day 6-DHS -more SW stuff along with shows-we did hop to Epcot for lunch, then a short rest and swim at resort before heading back for fireworks, then late EMH at MK-best time ever!*
Day 7- checkout day-sleep in, check out-DH took middle DD over to condo with most of our stuff while the rest headed down to enjoy SAB for awhile-they came back after settled and rested-lounged some more, then changed and headed to condo-Giordano's pizza for dinner
Day 8- sleep late, laze around - did go to Universal for a few hours in the evening but back early-Mexican place for dinner (Chuy's?)
Day 9- early early up and out to check into RPR, breakfast then Universal - took break in afternoon too
Day 10 up and out early-then back to check out and head back to parks for a bit-left early evening (rain) back to condo-carside pick up at Chili's to eat in condo.
Day 11-total pool day at resort (oldest DD and I did go to DtD for a couple evening hours-OMG do not take car-hop a resort bus or boat)
Day 12 - up early (for me) and off to DHS-final SWW-DH dropped me off then headed back to condo til rest were ready to come-through fireworks again(hopped to Epcot -love WS)
Day 13- up fairly early for drive to airport and home-due to time difference were back at our house before noon.
We got home and were glad to be home but not exhausted or even really tired. On a long trip it was so very nice to be able to take a break during day, or full day breaks. We did find that 10-12 days is about our "sweet spot" for a vacation. even a day or 2 longer would have been too much, and a couple days less would have left us with not enough. Since we are a family of 5 I am very glad we opted for a condo for the second part-the long trip would NOT have been as enjoyable if we were all still in one room-but that is just our preference

Next time DH wants to try a DVC resort if we stay onsite-trying to convince we need to do a cruise first...especially as it will likely be at least 2 years before we will want to go back-more new stuff needs to open (will
anything be left at Studios? or Epcot Future World?)
