Decide where in Cape Cod you want to stay. There are many small towns along Cape Cod Bay, including Orleans, Chatham and Brewster.
Consider the features you are looking for in a house such as how many people are going, whether you want to bring your pets, and whether you want to be directly on the beach, near the downtown area or up on a hill overlooking it all. These are important factors that will help you narrow down your search.
Find a Cape Cod realtor that specializes in vacation house rentals or use a trusted online site, such as Cape Cod Vacations. They offer many search options, including by area, house size or price.
Book early and pay a deposit. The booking early will ensure that you get the home you desire and the deposit will make sure it stays yours. Make sure you follow all the owner's application guidelines carefully, so you are not passed over because of a simple error.
