This is a very fun time with great views of all of Vegas, as expected.
I have done this at day time and night and really do think the night views have that extra sparkle of twinkle lights and think its a better option for a first time roller.
You can find coupons for this at many hotels that are Caesars owned or even ask at the total rewards desk.
Oh and make sure you use the bathroom before going, sounds simple but the bathrooms at the bar area before you get on are very small and cramped. You could be waiting for some time.
