We are a mid-50s married couple. This was our first cruise on Summit, though we have cruised on other Celebrity ships.
We used Celebrities air travel arrangements and were satisfied. We had to travel from the DC area to LA to board Summit. Doing it all in one day was somewhat nerve racking, because every travel segment had to work as planned. Next time I will travel the day before and know there is some slack.
We arrived at Summit about 3:30 PM. There were no lines. We completed the check-in and walked aboard Summit.
