Since you should give yourself 90 min to check-in, get wanded, get re-wanded etc, you actually got 99 min to play in fabulous wonderful LV. Traffic to the airport can back up at any time, and if a big Japanese etc tour group is in front of you, you need 120 min rather than 90 min. Obtain an airline club voucher or pay for a one day entry (typ $35-$50 and go to one with free booze) and hang out there and/or play the airport slots and watch the visitors winners come and go.
