The shopping is good there, fashion show mall is on the strip and the north/south outlets are easy to get to by Uber/Lyft.
Wynn is a nice hotel if you want somewhere a little quieter but personally prefer the other end of the strip (MGM, Excalibur, NYNY, Luxor all easy to get between if you stay up that end).
Main thing I didn’t realise before my first trip was how huge everything was and it actually can take a long time to get between casinos that are next door to each other as you might have to go upstairs, across a bridge, down an escalator and back inside or something like that (they all vary but don’t just look at Google maps and think you can walk the whole strip in a day like I did!).
You can use US Groupon to buy vouchers for attractions etc and play a game called My Vegas on Facebook for free to claim free show tickets/meals etc. Sounds dodgy but it’s not!
Also worth signing up to the players card in the casino you’re staying at if your DH will be gambling a bit. Take it to the membership desk before you check out and ask if they can comp anything.
High roller with an open bar is lethal but a lot of fun
and you probably won’t get tickets to any big boxing matches very easily but they’ll be plenty of places to watch/atmosphere if there’s one on.
It’s the sort of place you’ll either love or hate but I think everyone should go at least once as there’s nowhere quite like it!
