MO doesn't accept tips. It's their policy company wide. Their house car (a custom Mercedes S600 sedan) will take you anywhere you need to go.
MO has no need for 'lounges' as the whole hotel is only 330 rooms. They can easily take care of every guest rather than generally deal with the masses the way most other Vegas properties do.
No smoke
No casino (although CC is only 5 minutes away by foot)
IMO, best spa in Vegas. Very quiet. Very exclusive.
What other hotel in Vegas knows your name from the moment you check in and refers to you personally throughout your visit? Not Bellagio. Not Wynncore. That's for sure.
I'm a full-on convert: Mandarin Oriental is the cat's pajamas.
