My husband and I travel a lot using Princess cruises for our destinations. We are in our 40s. This was our 8th cruise-5th on the Princess.
Travel to Port of Embarkation: Make sure you do the longest part of your travel in the beginning--not the end. You'll handle it better.
Embarkation: They do the best they can under the circumstances. If you go into this not expecting perfection you'll be fine. I have no complaints here.
