We just had two departure days (not on purpose! We rebooked due to weather, so now sitting at MCO for a second time).
I am not a worrier about getting to the airport, but I definitely know people who can’t compartmentalize that off. It may be a lot to expect her to be able to relax and enjoy the extr time.
It really depends on your priorities and what you’d be missing by not using that extra half day. I tend to break our TPs up into morning and evening anyway (not sure when you’re visiting, but for heat / crowds), although you also might need some food by 2?
That said, on longer trips, I’ve really started to like ending with relaxed pool / resort time (and my kids remember the resort pools more than some of the rides. ).
ETA: If you take the opposite / super commando route, you could LLSP GotG (I would check TP for total time with preshow) and then transfer to MK and LLSP Tron / probably LLMP some stuff (depending on walking time more than anything else). You would want to tap and run in Epcot, probably, so you can rebook while on the monorail? Then you would end up in MK for easy exit around 1:45pm.
In case it’s helpful, here’s what we did on partial days this week - one with park ticket, one without.
On our first departure day (plane supposed to leave at 6:20pm - we knew it was delayed and were in a Lyft around 4:16pm from AKL):
Day 5 - we had unfinished business at World Showcase:
- Leftovers for breakfast sitting on the balcony
- Browsed AKL gift shop (time stamped 10:24am)
- Bus to DHS; Skyliner to International Gateway with a stop at Riviera for coffee and cookies (time stamped 11:04am in Primo Piatto - probably spent about 30 min here?).
- Got my remaining Kidcot cards and inadvertently walked the entire WS loop, pausing for last minute shopping (Mexico! Mask store in Italy!) and random storytellers in passing (Barn Santa in Norway, Witch in Italy, Hanukkah). Fish and chips pic time (first pic after entering WS) was stamped 12:01pm.
- Watched Voices of Liberty’s holiday concert for a second time
- Walked out the IG and checked out the decorations at Beach / Yacht + boat to Boardwalk. Beach Club carousel pic time stamped 2:15pm
We were two adults, so we could move efficiently, but we weren’t really trying, plus it was day 5 and I have blisters.
Inadvertent day 6 (rebooked flight due to weather):
I wanted to check out OKW and SSR for possible future trips. We stayed one night in CSR (Priceline deal) and took Lyft to OKW, ate breakfast at Olivia’s, then took the boat to DS and walked back to the SSR main carriage house, where we took a Lyft back to CSR. We also soaked feet in the hot tub, because blisters. . This was really calm / relaxing, although possibly boring for kids.
