thanks for the info, this was a game changer for me!

I ended up getting a GoH award and decided we want to stay there for 8 nights in july. So I broke it up into a 6 night reservation with GoH applied on booking on the app and a 2 night reservation without. All with points. It wouldn't let me do a 1 night reservation, so that's why there is a 2 night.
So from what i've read, I can just show up to the hotel on the day of my reservation and ask for a room upgrade since it's GoH and let them know I have two reservations. Best case scenario is they give me a room upgrade for 8 nights and breakfast is included every day. Worst case scenario, I keep the same reservations and rooms and get 6 days of free breakfast. Does that sound about right? I don't need to call ahead or anything?
Also, I am a bit confused on the GoH breakfast situation, it's a $100 credit per person or per room? And we can use it to buy snacks for later? We are 2 adults 2 kids under 12.

Finally, when do I rent a mini fridge? I ask for it same time I check in, or should I call ahead?
