I lived in Boston for 6 years, but that was . . . 22 years ago!

I love Boston, it is a small, manageable city IMO. Easy to get around, lots to see and do, no matter what your interests are.

I'm sure a website will give you many ideas: the Boston Common and the swan boats, top of the Prudential Tower, Fanueil Hall and Quincy Marketplace (great food, unique shopping experience!), the water front has changed plenty since I was there and has many great places now.

The afternoon tea time at the Ritz Carlton Hotel is fun if that is your type of thing (I enjoyed it plenty, my Mum was British) It is a bit pricey, and you may need reservations (can't remember) but really quite an experience. I think the Four Seasons Hotel did one as well, but I don't remember doing afternoon tea there.

Have fun!
