Have you stayed in Vegas Casino hotels? They are huge. Check in is usually 1/2 mike from the elevators to your particular tower. Usually several different banks of elevators per Casino hotel. You usually have to roll your bags directly through the Casino floor. You could check in, start using multiple entrances and roll suitcases in all day.
Not necessary. Every even slightly up-scale hotel I have stayed at has nice brass-toned wheeled luggage carts.
Load ANYTHING in suitcases, stack'em on the cart, slip the bellhop a fifty and give him the room number. He will happily take said cart to said room, remove the suitcases, and leave.
No multiple entrances needed.
“You usually have to roll your bags directly through the Casino floor”.
I checked in once at the Monte Carlo (slightly lower dollar place than Mandalay Bay) with one days clothing in a small carryon duffle bag, and got an extreme set of hairy eyeballs from bellhop staff for carrying my own bag.
I can’t imagine multiple trips of carrying suitcases going un-observed by those who make a living out of carrying your luggage.
Jus’ sayin’.
