Do you have an image of the exterior of your home? I think picking a color that coordinate with your home will be best for the guest house.

I don't on this computer. Main house is Brick facade with white stucco on the sides and Back. All house trim is white. Guest house is white stucco and about 10 feet from main house separated by a saltillo tile walkway.

The main room and bath don't have to "match" I'm more into coordinating than matchy-matchy. I'm all for the spa like pale aqua. Wondering if anyone has experience with any from Ben Moore. I know the light changes colors depending on location etc. but I would love to hear about some that have "worked" I'm afraid about veering into baby/childish colors.

Any specific colors I should take a look at?

FYI we painted the room and bathroom Benjamin Moore Palladian Blue with Simply White Ceiling and trim and it looks great with the new tan/beige carpet. I will post picture when it is fully decorated.
