I also might suggest the Mirage for your first trip. I love MGM and we are staying at Bellagio and Four Seasons at Mandalay Bay in a couple weeks, but I think Mirage might be a better first trip choice. I feel MGM and MB are towards the end of the strip, and frankly I think you would have more fun being right in the middle of all the action. Mirage's central location, and the resort/pool can't be beat. Sorry to muddy the waters. If you think of this as an exploratory trip and a chance to scout out other places you'd like to stay for future trips, it will take some of the pressure off of you! Have a blast!!!
