Wait, I'm confused. CSR is only $300 less than the GF concierge room? From what I've priced, GF concierge rooms are like $1K a night? You must have gotten a good deal.
I'd have chosen any value resort, as you can get up and out super early, and check into GF at like 6am (been there done that), and have access to the lounge for your breakfast (and mimosas if you so desire, LOL). I don't think it's worth paying any more for CSR than any all stars, if you're just using the beds for sleeping.
