Wash Your Sins Away

Hotel32 at The Monte Carlo
If you pay top dollar for these rooms, you can get Kiehl's toiletries in the bath.
The Hard Rock's Paradise Tower
Blah toiletries in the Paradise Tower which is one place where people really need a good scrubbing.
The Signature at MGM Grand
Sensible June Jacobs products and they smell good too.
The Flamingo's GO Rooms
Above and beyond the call of toiletry duty. Gilchrist & Soames travel pack.
The Mirage
Aqua Lime products smell very good but aren't quite upscale enough.
Wynn and Encore
Wynn Resorts-branded toiletries of course.
The Excalibur
Not sure if these are strong enough to wash off a night at the Excalibur.
