My vacation advice is walk, walk, walk and stay active
I tend to lose weight on vacations without trying which is one reason I really like vacations.
Chipotle is one of my favorite eating places as they exist in lots of places and it is easy to get a good, low calorie meal there. I like their salads, my husband likes their bowls or splitting a burrito is another option. Just stay away from the sour cream and cheese and I usually ask for guacamole on the side and add how much I like.
I looked at the restaurants in Ocean City and I don't know any of them or the ones I do recognize, I don't know the menus.
