You may want to ask this question on the Provider's Board.  Many of the ladies on their have toured Boston.

Otherwise you run the risk of LE knowing where you are staying.  You will also have guys telling you to stay in a particular area for their convenience, but it may not be the most central place for you to host so that you can maximize your visit.

You could mix it up by staying in the Back Bay, Cambridge and even hope on a train to host north or south of the city.  

Just a friendly suggestion about using the resources available on the Provider Board.
Nice ladies on there.

Good luck,

Kate
