Well Karen, for me, you can't top the Paul Gauguin and Tahiti. But...the rest of the Regent fleet are actually more luxurious, as cruise ships--larger cabins, wonderful food, great service (albeit a little less casual and friendly). After twice on the PG, we ventured onto the (now defunct) Diamond, and have since done Voyager and Navigator. All I can say is, "wow". But we've been back to the PG twice since, and that's where our hearts will always be.
Glad you had such a great time.
