Las Vegas - Wild Bills Gamblin Hall [ formerly the Barbary Coast hotel] on the Strip every aft in the downstairs bar go rest your feet for a while go and see Big Elvis perform, hes good, great atmosphere all you have to do is buy a drink its a free show.
Also check out the free overhead show at the Rio hotel, its on ever other hour, go to the first floor and look over the balcony you will be eye level with the floats.
Go Downtown any evening o see the lazer show [ free] its like one big street party maybe see a proper show whilst there, everything is much cheaper, bars etc than the strip.
New York try the revolving bar in the Marriot Marquis hotel in Times Square where Arnie took the white horse up in the bullit lift in one of his movies True Lies , also their steak restaurant is really good.We tred to go to Kayote Kates bar in NY but when we got there it was shut !
Wish it was me going ! have fun
