We went in June, had a blast! Here are my answers:
How old was your infant when you went? 6 months
What ship? What route did you take? NCL wind, inside passage
Did you do any shore excursions with your baby or just visit the ports? Ketchican - halibut fishing, Juneau - bus to mendenhall glacier & went hiking, Skagway - rented a car and drove in to the Yukon
What was dining like? If baby fussed, we would leave, they were always happy to give us the rest of our meals to eat in the cabin, they always offered to get something special for the baby, but he was still just nursing at the time.
Did you use in-cabin babysitting? No
How was the staff with your DD/DS? How about other passengers? Everyone was great, never noticed ayone complain or avoid us and it was actually hard to keep people from trying to touch him even while he was sleeping!
Any issues that you had? none
Do/did you wish you had left them at home? Not at all, in fact, my husband commented as we were leaving, that at least we got to bring the best part of the trip home with us, meaning our baby!
(I don't remember there being any sex though)
