We're normally in synagogue for the holidays but managed to unknowingly book a cruise that was on 1st day of Rosh Hashanah. There was no rabbi but services were self-led. They provided prayer books, challah, and wine.sinc3 it was a TA we had met some the other attendees at Friday night services. If you want something special call or email mbayley@rccl.com and someone will help. Enjoy your trip.
