My DH and I did Vancover to Seward the week before the 4th of July a few years back and it was HOT! Just a warning for anyone packing for at rip during the summer because it seemed like we were the only ones on the ship that were prepared for warm weather. Do make sure to bring plenty of clothes for cool weather as well. Okay, now that I got that first thing off my mind...
This was our first cruise (we were in our early 30s) and we left our kids at home. We loved the Alaska cruise because the scenery was fantastic and we liked to do the adventureous shore excursions. That said, we probably wouldn't go HAL again because it was just too slow for our pace. Because our kids were very small and energetic, and because this was one of our first times without them, we actually enjoyed the amount of "downtime" we got. We spent entire days just sitting on deck watching the scenery go by... but there was little else to do on the ship for us. I played bingo more than I ever thought I would, that's for sure; and I actually LOST weight because there was so much time for me to spend in the spa/workout area (fantastic views while doing aerobics on deck!). We were also the only "young" couple on the ship. Every person at our table of 8 had children our age. We had a blast with them, and really did enjoy ourselves, but found ourselves looking wistfully at the Princess and Norwegian ships that seemed to follow us from port to port. I do think, however, that they both turned back and did a loop, while we continued to Seward. I know for sure that we were the only ones in port in Seward, the building we exited through to catch our buses/cabs, etc. was just a large pole barn. Absolutely no ammenities. Very Alas-kan.
If you've been on other, bigger, flashier ships, you will likely notice a huge difference with HAL. We'd never been on a ship before so it wasn't a big deal, but when I have looked at other people's pictures from other ships, I see that in some areas we were a little more sparce (about 4 stores rather than several floors, etc.).
We arrived a day early to make sure that we wouldn't wind up missing the ship due to a flight problem, and just took a cab from the hotel to the port. Very easy.
The service was fantastic, the ship was clean and well maintained and the food was good. Just a bit slow for us. But we adored Alaska and plan to take the kids when they are middle school age. I think it is one cruise that older kids would really enjoy because there are so many interesting places to see and animals to learn about.
