Just got back from Vegas again at 3am. Major flight delays due to incoming late plane. Was 107 when I left. So hot that the plane was delayed leaving awaiting an OK to taxi to a much longer runway because the heat makes the air less dense and they need more distance to take off :(
Tips:
Bring Lip Balm. Air is bone dry
If you plan on being outside at all, it goes without saying sunscreen..
At the same time, you can hang meat in some of the session rooms. So even you 'manly men' better bring something you can slip on and off quickly from room to room.
If you get bored (how could you with all this edge of the seat content planned), table limits are lower during the day than at night :)
They say the Michael Jackson One show is excellent at the Mandalay. Haven't seen it myself.
