Anyway, the Back Bay is very easy to negotiate. It's located basically between Fenway Park and the Boston Public Garden east to west, and between the Charles River and Tremont Ave north to south. And the east/west streets are named alphabetically, from Arlington to Hereford. And then there's Massachusetts Ave. I'm not sure where that one came from. Within those borders are about a billion hotels, restaurants, clubs, and overpriced apartments in old brownstones. It's a nice, safe neighborhood to live in and visit, and any hotel in the area will be great.
I suggest that you try the discount sites, like priceline, orbitz or even expedia. Select locations for either the Back Bay/Copley or Downtown, which is right down the street, and even includes some hotels on the eastern edge of Back Bay. It's very likely there will be extremely reasonable prices for super-nice hotel rooms--I got a room at the Plaza for less than $80 on a weekend night, and that included breakfast. Also, any hotel in either of these neighborhoods will be just a quick walk or $3 cab ride away from the Jurys.
We've reserved a block of rooms at the Jurys Hotel, where the wedding and reception will be held. However, I'm not going to lie to you--it's wicked expensive, even at the reduced rate. There are a TON of hotels within just a few blocks of the Jurys that are really nice, unique and much less expensive.
Here's a list of some of the neighborhood hotels and their websites:

If you find a great deal elsewhere, the public transportation system in Boston will get you to within a block or two of wherever you need to go. However, I would advise against staying anywhere in Dorchester, Roxbury or Revere. A lot of these areas just aren't too safe, and it's likely that hotels will be less than clean. But please just give me a call or send me an email if you have any questions at all or need some help!
Also good to know--www.cheaptickets.com appears to have inexpensive plane tickets (non-stop) from Detroit to Boston over that weekend. If you're planning on driving, please let me know and we'll see what we can do about getting parking set up for you.
