Edit w/MGM hotels Vegas
In a fluke situation, I used my 2 Edit credits in Vegas at MGM resorts. Vdara booked in June for July and Park MGM for last week.
A few things I learned:
(1) Download their app--it will let you get a digital key and never mess with the front desk.
(2) Once within the 72 hour check in window, call the front desk to confirm the $100 credit. The Vdara stay only had $60, which they fixed.
(3) On that same call, ask for early check-in or late check out. I always spoke to super friendly people.
(4) Only certain restaurants are eligible for the $100 credit, but you don't have to use it all in one place. Note it must be for consumable food. Buying a bottle of wine to go at Eataly will get billed. Full list is here:

(4a) Tips don't count in credit, which was fine with me.
(5) Keep checking the room price. Both of mine went down and I did the cancel and rebook thing. The credit worked as it should both times
(6) I didn't get upgraded, but I also wasn't looking for that, so it didn't bother me.
