Which Hotel? Please weigh in on choices.

I (52F) am going to Vegas with 2 friends (60F & 52F) first week of February and have tix to Backstreet Boys concert at the Sphere that my SO paid $$$$ for as a gift to me. Friends are not paying for tix. We all like nice experiences/hotel stays especially on vacay, but we’re all also very down to earth and not hotel snobs in the least (we all regularly stay in Fairfield Inns, Hyatt Place, Home2Suites, Towneplace Suites on personal trips.)

Friend (60F) and I have been to Vegas for work many many times and we’ve done a good bit of dining, shopping, and nightlife. We’ve always stayed at Venetian/Palazzo except once our company put us up at Mirage (we were completely underwhelmed by the room, hotel common areas/restaurants/casino were fine. She won’t be arriving until around midnight Wednesday night and departing Sunday.

Friend (52F) is going for the 1st time and she and I are going in 5 days/4 nights earlier than Friend (60F) so she can explore Vegas. She and I will be there Sunday-Sunday.

Venetian/Palazzo has a $1,000+ rate for Friday night and $597 rate for Saturday night, so ~$1700+ for just those 2 nights and brings the total hotel cost to ~$4000 for the week including resort fees.

So we looked at other possible options for the week and came up with:

1. Luxor 2 room tower suite with 2 queens in bedroom - $1800

2. Paris 2 Queen suite - $1700

3. Flamingo 2 Room Neapolitan Suite 2 Queen in bedroom - $1500

4. Flamingo Go Executive Room strip view or Habitat Tower - $825

The pricing is extremely different vs Venetian - definitely enough that we can’t not consider staying elsewhere and it might be fun to explore/stay at a new place, but Venetian is familiar and has the interior hallway to the Sphere. Really comfy beds and larger than average hotel room are necessaries.

Thoughts on these options, which you’d choose, and why?
