Have you ever been before? I love the shows! I did a go pass in Vegas the last time I was there and we saw three shows for $70 each - smaller ones. Beatles Love is a great show - not sure if it's still there or not. I always just enjoy going up the strip and people watching too
We are doing Vegas also and we want to focus on the activities rather than the partying. So we want to do the gondola ride and the Venitian, visit the Eiffel tower and have drinks at the stratosphere bar. We also want to do Top Shot and CSI the experience and the zipline on Fremont Street.
Definitely splurge on a nice 4 or 5 star hotel. It is so worth it and much cleaner/safer. Cirque du Soleil is always amazing! If you want a more affordable option too, it's fun to just walk the strip! The hotels are over the top and a lot of them have cool stores/shopping. We've been to Vegas three times and never had to spend money on partying/gambling. Always something to do!
