Not sure if everyone here has heard, but the pre-cruise and during cruise add-on packages through Adventures By Disney are now availalbe for booking. (There is also a pre-cruise train trip to Whistler available - it is through a Canadian provider and not ABD.) Check out the
DCL website!
The Vancouver pre-trip and the during cruise add-on both sounded fantastic. So much so that my parents and I decided to do the cruise add-on.

It looks like our port days will be very full - but it also seems like we will maximize our Alaskan DCL experience with plenty of time on the sea days to explore the ship. There are also some nice inclusions on the ship- such as a Palo dinner with wine, first day and last day receptions, inclusion of all gratuities (including those for ship staff, but not for the adventure guides), plus a photo package (including CD) of all onboard and offshore photos.
It seems a bit weird to have added this on before DCL listed their official excursions, but at the same time it's nice to know that our first ever cruise vacation is now pretty much completely "worry free". (Well, except for booking flights and our pre-cruise stay ... but I like hunting for air and hotel deals, so that's more than manageable.
