Berreez,
What you can expect is a great time ( no matter how you bowl )! The tourney is well run by the High Roller people. The best thing to me on my first trip to this tournament( being a retiree myself ) was getting to see the people I had not seen in years, this is as much a reunion as it is a bowling tournament.
As far as staying at the Gold Coast goes, obviously it is very convenient but there are better options and the Orleans is one of them, I prefer staying on the strip.
Having one active duty member will put you in the active duty division for all events, not just the team event, reason being is there is a Team all events event. That was my circumstance as well for the past two years. One thing you should know is that the Retiree division is where the money is at. The retiree division normally has more entries that the AD and Senior division combined. last year 175 teams entered and the Retiree division had well over 100 of those teams.
The PBA exempt tour will have two stops in Vegas during the time frame of the Military tournament ( The PBA Exempt Doubles Classic and the Tournament of Champions ) both will be held at the Red Rock Hotel and Casino.
One thing to know is you will always be on the go, remember Vegas never sleeps!
Have a great time.
