OP i just went to vegas for SB 3 weeks ago so I can give u some pro tips.
One that place costs a shit load of fucking money. Oh my god, like go there set aside x amount of funds, and do not expect to come home with that money. If you are there for 2 nights, I suggest around $500 or so. Not including the hotel....
Gambling, it is stupid. Every game there the house always has an edge. The only game I will play from now on out is Texas Holdem, only one that has odds of winning. But I suggest you play Blackjack or roulette, stay away from slot machines they consume your soul.
Go to a liquor store and buy a handle or two of something, and make your own drinks. It is true that while you gamble you get free drinks, but honestly it can take a long time for the server to get to you. It is just better to make your own drinks in your room and bring them outside.
There is no open container law in Vegas, that means whatever you make in your room, you can take it with you to pretty much anywhere in Vegas, except for like clubs. But you can take your drink anywhere outside, walk on the strip, go into other casinos, it's pretty cool.
I don't know much about hotel pricing, I didn't book them.
