First stop is Philadelphia and surrounding area of Pennsylvania (20th through 24th). I was once thinking about moving there, and there is at least one nearby college town I want to check out, so it seems like a good place to check out. I don't have any specific sights in mind but figure I'll check out some tourist websites or see if there are any tour buses I can ride around. That's always been a good choice on exploring a new city in the past.
The second stop is Baltimore where I'll catch a seven day cruise to the Eastern Caribbean (24th through 31st). There will be three days at sea and three stops for Grand Turk, Half Moon Cay, and Freeport before returning to Baltimore. I've glanced at the excursion activities and so far I'd like to pick one for kayaking, snorkeling, and possibly horseback riding. There will also be plenty of beach time at one of the ports.
Last stop before returning to Seattle will be a couple of days in DC (1st through 3rd). I don't have anything specific in mind at this point (any of my DC friends want to do lunch/dinner?) though I might just grab a tour bus here again as well. I've done it before and think it would be nice to do again.
Once I return I'll look into a trip to Vancouver to visit Wreck Beach again. It's been on my to-do list since I went last year.
Past that? Dunno. Maybe work, maybe Hawaii. I have enough miles to cover a round trip to another continental state or most of a round trip to Hawaii. I think I'll do an international trip for summer next year.
