Here's a great list, updated with current party offerings:
MMILV facebook page viewing party info
So many options - with just 2 of you will be a bit easier to move around. Saturday viewing parties not really necessary as many are Vegased out already or just with the lighter game schedule (2 games aren't running at the same time until early/mid afternoon) everyone doesn't make the effort.
A lot of the pay parties might be sold out - read the reviews/previews. Many of the pay parties are very overpriced for what you get, especially since she's into liquor and not beer. For the 2 of you maybe one of the non-sportsbook venues for Thursday, where you can reserve a table in a restaurant (with maybe a table minimum) and get better food and drinks.
Warning: all day (esp Thur & Fri) is ALL day...if you think you'll roll in 30 minute prior to the 9:15AM tip and get seats, get your bets in at the window.....think again. Games will run until 10PM. Can get long for those who don't love the hoops THAT much. I have no such problems....is it 3/15/18 yet?
