I've stayed at the LVH (formally the Hilton) multiple times, mostly due to the low price deals they gave. It has a monorail stop, so you can get to the strip easily. Though I usually get a rental car so I can go to the strip clubs, to see my favorite incall girl, and to go to Blueberry Hill. Nice, clean rooms with an in-room safe.
Also, a benefit to the LVH is that there's no security at the elevators.
The Excalibur is my second choice. If you are like me, you don't need a fancy room in a fancy hotel. Just some place to sleep that's not a flea-bag (and not an embarrassment for your outcall date). It's right next to MGM and NYNY, and close to Luxor, so you have good walking options. Though admittedly not as many as if you stayed more central on the strip like TI or Mirage. And the closest monorail stop is in the MGM. It might not seem far, but it's quite a hike to get to the station.
The Excalibur will often have security at the elevators. I'll often 'lose' my key and request a replacement. The hotel will deactivate your original keys and give you new ones. These dead keys can be given to your date downstairs, so you and she can go to the elevators separately.
There's a half-price ticket office close to the Excalibur too, if you want to try to get cheap tickets for a non sold-out show. I think they open at noon, and it's nice to be able to just walk down there easily and not make it an ordeal.
The bridges that connect the 4 corners around the Excalibur are often populated with working girls, if you are into that sort of play. The LVH can sometimes have casino girl action, since it's a prime convention center hotel option
