We had a great time but it's due to the fact that we were traveling with 3 other families. Overall, for our first time cruising, it was a good experience.
Seattle Embarkment: We arrived at the terminal early (11 AM) which gave us lots of time to check-in with no line. There were lots of agents available so the check-in process was very quick. You can even arrange/reserve/or change your dining option before boarding. There was a table with staff to assist you with this. We found out Lobster night will be on the first night so we switched our Cagney's reservation to another night. Note: there was a deal where for $57/adult, you can dine at Cagney's, Le Bistro and Mama's Kitchen (aka La Cucina) which was what our group pre-paid.
Dining:
Cabin 11546, midship suite with balcony. Great location since not too close to noisy elevator but middle enough not to feel ship movements. Generally quiet since we did not hear any noise from the pool area above us. Most noises were from unruly kids running in the hallway. Cabin is on 11th floor and Garden Cafe (buffet area) is on 12th; was close enough for us to just walk upstairs instead of taking the elevator. Room is small but well organized with closets and drawers. Another plus is bathroom has a tub instead of just shower; this may seem small but was a big plus when we need to bath our 1-year-old. We had a king (2 twin converted) bed and a sofa that converted to a full-size bed. The king bed was comfortable but the sofa bed was on a hard size. I brought a mattress topper which helped soften it.
