In general, the more popular a destination, the costlier it will be to go there. It’s the simple supply-and-demand equation, and if you’re adding to the demand then you’ll pay for it. So take some extra time to research destinations that aren’t as well known.
If you have time to put into it, you can find beaches, mountains, resorts, spas, family camps, cruises, urban destinations, cabins, outdoor adventures, riverside cabins or whatever matches up with your ideal vacation … just not in the most obvious places. Do a little research, and you can have the same great vacation for less cost.
