Congratulations!
Have you ever been to New England?
There are some beautiful places up there.
Lodging from quaint B&B.s. to four star resorts.
Food from clam shacks to ultra fine dining.
Mountains or ocean.
Newport, R.I. is a great place to spend a week. The bay, the ocean, the old robber baron mansions, and great seafood.
Cape Cod, the White Mountains in N.H., anywhere in Vermont, Maine coast or mountains (gotta watch out for the Maineiacs, though

).
Hikes, day boat trips, fishing, history, and food. Lots of good food.
Of course June is the high season, so if you want to go, you'd better plan right now.
No matter what you do, have a great time.
