Reasonably priced beachfront hotel ????

Ok......so my very best friend is tying the knot and I need to whisk her away from the drama for a few days(...that IS the maid of honor%26#39;s job!) and I need suggestions. Here is the criteria:

Clean hotel

On the Beach

Walking distance to town (If possible)

I%26#39;ve been to Newport(little pricey for me), but that%26#39;s about it for RI. I was looking for some insider tips.

Thanks for your help! :)

We were going to go in the beginning of September and really only wanted to spend about $100 a night.
