 staying in Wellfleet
I would suggest staying in Wellfleet as there many cottages to rent and many nice bay beaches without nasty waves where kiddos can swim in safely.
There is also a cute little downtown, several nice restaurants, and Provincetown isn't far away. You can do whale watching in Provincetown, though you may want to reconsider this if you are traveling with small toddlers as they'll get seasick. |
