LeeAnne,
Knowing how active you are, and having been both in Alaska and on the PG, my observation would be to take the PG in 2006. It is a totally either Veg out or be very into the watersports type of cruise. The scenery is incredible and the ship and it's service lovely. And you can say that statement about Alaska or the PG. While there won't be another MUSH after 2006, there will still be Alaska on an RSSC ship or anohter group another time, and they may not be a PG at all afterwards.
