I am a plat - so nothing waived

Daily:
Room fees and taxes - gratis
Beach gratiuity $5
Resort fee (beach towers) $49.95 + $5.99 VAT

IF you are a diamond - you get beach towers and no waiver of fees
BUT
If you are a Diamond (>40,000 Tier Credits) AND it is off-peak (then you get Royal tower instead of beach also) or Seven Stars anytime
- then you should get resort fees waived - I never asked if it was off-peak because it didn't matter for me

Make sure to check restaurants you want to dine at, a ton are closed Sun/Mon cause there is literally no one there - although depends on when you are going

So, I guess if your reservation is for Royal towers you may have an off-peak or be a >40,000 Diamond

To be honest, my Platnium is due to retired military, I have like 2200 tier credits as I don't gamble enough to matter, so I rarely pay much attention to the higher classes as I will never get there nor have any real desire to attain them - I am grateful for the 3 free nights and leave it at that.
