i agree with jersey city... it's right across the harbour and you can take the PATH train straight to WTC station or another station like 34th st, i can't remember exactly which one. i stayed at courtyard by marriott jersey city, it's actually right next to the PATH station. it's super convenient and i think it was around $175/night but we did go during high season (june). i agree with all of aliburke's advice here!is it already too late to give advice on this? i hope it's not! but jersey city is PERFECT for staying close to the city and saving money. the hyatt in JC is probably pricier than others in JC but it is on the water and has uninhibited views of the city! it is also RIGHT next to the path station do you could be in lower manhattan in FIVE MINUTES!!! there is also the doubletree in jersey city. or alternatively you could look into the sheraton in weehawken (also amazing views of the city and right on the water) which has the ferry right outside that will have you in manhattan in 5 minutes as well!
