My husband & I sailed on the Grand Princess June 29th, it was the inside passage cruise.
Embarkation in Seattle was organized, but we did have to wait in lines to go through security, fill out health f orms and then check in. I would say the whole process took around 45 min.
Once on board we went to our cabin a mini-suite on Dolphin Deck. We checked out the cabin, then we started exploring the ship, we had a bite to eat then had to return to our cabin to get ready for the emergency drill. Not bad, it took about 1/2 hour and it was done inside the ship which was nice.
