price really depends on where the hotel is located.
the closer it is to popular area, the more expense
just NYC for example, you can find some at $30/night (remote area, need car) or $150/night (regular) within the city or even higher for brand name
go to
www.hotels.com or
www.expedia.com or
www.priceline.com , etc. air fare/hotels/vacation search sites for the pricing and locations
For NYC, day's inn is in chinatown (manhattan)
there is a very good on in Flushing (another chinese hotspot but remote a bit for site-seeing)
