I cannot recommend Cannon Beach enough. We fell in love with it & our daughter who is almost 3 1/2 still talks about her "beach" from last summer!
We stay at the Surf Sand resort. Right on the beach, cabana boys to help, hot dog roasts for kids, bonfires at night, ice cream socials...it's the best! They redid the hotel a year ago too & it's very spa like. Great toiletries & even a plasma tv in the bathroom!
Oh, & you can get a package where they set up a tent for your child compete with a sleeping bag. It has a sand bucket filled with goodies like cookies, temporary tatoos, & a flashlight. My daughter was in heaven!
I know I sound like I work there...LOL...but we cannot wait to go back this summer. If you go there, breakfast at the Pig N' Pancake is a must...a mom & pop place with great food.
