Just got back from 6 nights at SLS - it was phenomenal.
The restaurant options are great, the casino is really fun and lowkey and we found 99% of the staff to be cheery and fun.
Each day/evening we would venture out to other casinos and every single night we would decide to go back and gamble there. There were a few dealers and floor staff that were a blast to be around - we played baccarat- a game I had never played - just to be at a table with a dealer we had a blast with earlier in the week.
This was my 3rd trip to Vegas and I booked the hotel through priceline express deals not caring where we ended up - from now on, it'll be straight SLS, it was that good.
