The High Roller is a must. The views are incredible and the wheel itself is fascinating, from loading to the top to your return, just seeing how it all works is a treat in itself. When we made our room reservation at Harrah's, we were given the option to book a daytime ride for two for $20. We checked into Harrah's at a kiosk, no mention of the High Roller, but I went to the desk later and they gave me a prepaid voucher, which we presented at the ride. They still charged my room $50 for the ride, so on my final bill there was the original $20 plus the $50, $70 total. I mentioned this at the desk and they happily removed the $50 charge. I felt like it was a scam, that the High Roller was hoping I wouldn't notice. Didn't appreciate that. Great ride though.
