In the 1B/2B at Riviera, you're in the king bedroom, and it gets VERY dark in there. The only annoying light was the smoke detector green/red dot. If you use a sleep mask you'll be fine, but I am a VERY finicky sleeper and need conditions freaking perfect to stay asleep. I would just pack the little round Band-Aids for blisters and throw one on top of the light. My husband is 6'4", so he just reaches up and does it for me.
In the Riviera living room, where our kids sleep, the light from the balcony shines RIGHT on my son in the trundle. There's like a 1" gap, and only thing I can think to do is lean some couch pillows against it to push it against the door to cut out most of the crack of light. We clip the curtains in the living room shut with pants hangers for the main living area/our daughter on the Murphy bed.
I do find there's a TON of little lights in the kitchen area, but they don't bother our kids -- and our daughter uses a sleep mask, too, LOL. They won't affect you in the 1B/2B because you have your own separate room with a door and all that jazz, so that's fine.
PIT studio was actually VERY dark! Almost TOO dark, because their light switch situation was confusing. No issues with little lights, and the curtains and sheers worked perfectly.
