You have also probably pondered upon why exactly do some people chose to travel whenever one else cannot? Well the answer to your questions is one in the same thing i.e. the off season. The off season is when people are not travelling and this is when airlines, hotels and tour operators will reduce their costs. The lower they are able to get in the way of prices the lower will be what your total trip will cost regardless of what package you chose and even though some trips are cheaper than others.
How much does the airfare cost?
One of the major components of a cheap trip to New York is obviously the air fare. The higher your air fare the more you can expect your trip to end up costing you. If you are purchasing a vacation package then air fare is something which shouldn't be a big problem if you are travelling during the off season or if you are travelling during the busy season you can get away with cheaper rates by booking your air ticket in advance. The more advance you book your ticket in the bigger will be the discount that you expect. However, if you are planning on flying just prior to a big holiday season such as Christmas and New Year it would be a good idea to book your ticket at least 2 months in advance since doing so will save you a lot of money.
Pack everything you need
Many people in their effort to travel light forget to pack some of the most important things to them which they then end up buying. While New York may be expensive and yet cheap at the same time depending on where you shop if you have something at home there is no reason to buy another one in New York. In order to save money you should take what you need, after all your objective should be to travel cheap not exactly light.
Make a list of what you will see
The best way to travel in New York is to know where you want to go and how much it will cost. Attractions such as Central Park, the National Museum, the ferry ride to Staten Island etc are not expensive but knowing that you want and need to do these things on your trip will allow for you to plan in advance. You should also set aside a budget, a certain amount beyond which you do not want to spend which will help you stick to what you need and want. New York is a beautiful place to visit regardless of when you do so it pays to take your time and visit the city when things are at their record low in terms of price.
