Fun experiemce! Beware that afterwards if you want to buy the photos they take before you get on the High Roller, they cost $35 for one photo pr $55 for three.
Just go down to Photo To Go and take a picture in their 'Welcome to Las Vegas' cutout, get the first one free and the additional small sizes for $1 each. Theu have other sizes and types for other pricing.
Enjoy!
