Thanks, ga-zillions! You've made me re-think our plans.
I wanted to stay close to the airport because:
a) I always have, which isn't always the best reason to do something

b) we have a very early flight out to London on Sunday morning and we can actually sleep for an extra bit, if we don't have to be ready and waiting for the shuttle/taxi/whatever wheels we choose. I was actually looking forward to a short cab ride to the airport, or the even shorter hike from the Sheraton to the terminal.
I get it, though, about the sterile atmosphere surrounding the airport hotels. With a 17 year old with me, downtown just might be the best thing for both of us.
I'll give this some thought and come back to you for your suggestions about a great hotel/inn/B & B in the downtown area...I've only stayed with family in the downtown area. Thanks, again!:-:
