Why do you not need to spend a lot of money every day if you got a sunny place for your holiday?

When you go to the beach for vacation, normally you bring things with you. Things like water-bottles, towels, and toys for sandcastles are all cheap and easily accessible.

However, if you go somewhere cold, you have to bring much more. A thermas for drinks, jackets, sleds, and other equipment tends to be more expensive and less accessible.
