We stayed at the Hotel for one night, to visit the park one day and other Lantau sights on the second day. This was on a Monday so thankfully not too hectic, I can imagine it being quite crowded on peak seasons
Check-in was as fast as it can be, provided they also give you the park tickets, Fast Track Passes, etc. The kids are entertained in the little TV room while we iron out the paperwork.
The room and the little Disney details throughout make it a memorable experience for the kids, and they are doing a great job in the pandemic to keep things clean and organized. This means that you need to pre-book a time for breakfast, a slot for the pool, etc... The grounds are kept spotless.
The only downside was the over 1 hour wait for room service for dinner. After a long day at the park it was a shame to have to wait so long for the food - which in turn was OK.
The pool area is very nice, and the convenience of staying by the park allowed us to stay in it until it closed and then take a short walk back (could have taken the free shuttle also)
