couple of days in cape cod

Where on the cape? What kind of food do you like? What's your price range? What do you like to do (beaches, hikes, museums, art)?

Hi,actually I still do not know exactly where.
I was in Cap Cod - on a sailing Camp - something like 20 years ago,and I've never been back there.
So my visit is kind of nostalgic journey to a place where I've been when I was a child.
Regarding the food,obviousy it's seafood.
Regarding the price range,well,I don't know,let's say I like good food and nice places,better if they are not too much expensive.
And about what I like to do,not much of museums,yes to beaches and hikes and visiting villages,taking pictures of nature,this kind of things.
Please suggest me the best places you know !!!
