Yes there are a few inexpensive hotels in Venice although I don't know that I would advise staying at them. Many European hotels do not have A/C which can prove un-comfortable during the hot and humid months.
The atmostphere here is great unless you're a king and are in 4/5 star hotels then any decent Corralejo hotels are good. Good luck and have fun!
Yes, Egypt has hotels.
Orlando is known as the world's capital of amusement, or the land of a thousand hotels. There are hotels for every conceivable type of budget and preference. And guess what: every single hotel in Orlando wants your business. Think about any major hotel change and go to their website. Chances are that they will have a hotel in the area. Check their prices and accommodations and compare. You will find many hotels that may not be within walking distance of the amusement parks at great prices. Many of these hotels offer free shuttle service to and from the attractions.
No, there are no hotels in Vatican City.
Unfortunately most of the decent hotels in New York City are not very cheap. It is like any big city these days I guess, and you are likely looking at around $300 and up per night. I did find this website that offers cheap prices for stays in NYC. http://new-york.hotelscheap.org/

Alitalia is one major airline that goes to Venice, Florida.
There are hotels in Massachusetts which are highly rated and there are those which are poorly rated. As would be with any place there is a mix of good and bad hotels. I cannot say though if Massachusetts hotels are any higher rated than other State's hotels.
