Let me start with the negatives and why I only gave three stars:
Grossly overpriced. Yes it is Vegas and the strip, but it's not like I have a private pod or free alcohol flowing as I boringly look out at the landscape. Oh, wait. I have a 'high view' with A/C blowing on me. There's the savings!!.......not. Also there shouldn't be day to evening costs. Not to mention it's about 30 min. ride roundtrip. It's just not the best experience in town.
We did it for that 'once in a lifetime' feel and I'm happy to say I have been on it but that's about where it ends.
Save your $$ and visit the top of Stratosphere; eat dinner in the Paris eiffel tower; or just take a ride on the strip monorail. You'll have a more enjoyable time.
