cmaxx, all that flying in all differant directions will be a killer! i would also go to vegas last and for atleast 4 nights but pref more. its a great fun place and if you go last it will give you more relax time (ie lie ins!) than new york, where you to tend to get up early etc. a great trip we just did wasnyc, san francisco (great place) then vegas. we used united all the way and i do beleieve they fly direct to and from nyc. try there uk website or call centre. once again though i would highly reccomend going to vegas last. having said that the usa has alot more to offer than just new york, as great as the place is you have just been and for two weeks. as a tourist you must have done it to death, try san francisco and vegas you wont be dissapointed. both have loads to offer. both totally differant to nyc and each other. whatever you decide have a good one!
