I thank you one and all---
I did consider an apartment but thought it requied longer stays..I am checking into this idea.
Streetwise map is wonderful--I will check out the Frommer's also..
As usual Fodorite ARE more valuable than most guide books because they are personal experiences...
So now that you all have helped me "calm down" I can start planning..
Thanks again...

Let us know, from time to time, how the planning is going. Happy Travels!
