My extended family visited Alaska this summer. We had three generations ranging from age 13 to 73. All told we had four cabins...three on Deck 8 and one on Deck 7.
Our flights were arranged through the travel agency and we flew from Louisville to Atlanta and then had a long (5-hour) flight to Seattle. Atlanta's airport was hot and crowded, but a necessary evil. When we arrived in Seattle things went very smoothly. We met the Royal Caribbean representative near the baggage claim, checked our bags, and waited perhaps ten minutes for a bus. We were at the terminal within 1/2 hour and went through checkin without any major problems (slowed a bit because one member of our party was in a wheelchair.
We were on board by 2:00 and had time to explore a bit (and have a cocktail or two). The mandatory muster drill was almost fun. Some of us changed for dinner and hit the happy hour at the Schooner Bar before our first dinner.
