While here in Vegas, we just went to the Avengers Station attraction at the Treasure Island Casino.
It WAS cool, IF you're a BIG Avengers fan. Well, I am. It was too pricey, probably worth half what we paid. BUT they have LOTS of Marvel stuff. You could get your pic taken on Captain America's WW2 motorcycle, and they had a row of the most iconic Iron Man suits, ESPECIALLY the Hulkbuster suit.
Did some pics and selfies in front of them. Some interactive electronic stuff, including a group fight against Ultron at the end. But none of that was especially entertaining. What was cool were the exhibits. I tried but failed to lift Mjollnir. Sadly, I wasn't worthy.
Doing some shows this week. Piff the Magic Dragon tonight, Blue Man Group tomorrow, and David Copperfield Tuesday. I'll let you know what I think.
