I cannot pick just one. I have some that were my least favorites but they were still good.
The WAVE cruise was incredible because everything was absolutely amazingly PERFECT, the ports, Service, the ship and particularly being with great friends;
The 1st Alaska cruise in 2001 on the Mariner was amazing -the scenery awe inspiring perfection, the brand new ship, the great service and we did some really great excursions and some lifelong friends we made onboard;
The Panama Canal on Mariner was a great combination of rest, relaxation and great people and the Canal a wonderful experience. I will never forget standing at the front of the ship with my Frank and Frank and Joann as Terry Breen narrated the final lock after an incredible dinner on the pool deck.
SAND was like that too - the ship was the destination for us and everything was wonderful.
The Paul Gauguin setting of the spectacular islands of Tahiti (but our least favorite of RSSC ships) and our first escorted by Ngaire cruise.
No, there is no one favorite. Well, maybe the next one will change that - but I will never really be able to choose and as a female I will have the ability to change my mind if I did!
