I sailed on Regent last year from Monte Carlo to Venice. I have previously sailed on Crystal. I think Crystal was far superior to Regent. I'm sailing in August again on Crystal from Barcelona to Venice for 12 nights and really looking forward to it. I doubt I will sail on Regent again. I was only on Regent for 7 days and we were in port almost every day. It is nice that the shore excursions were included in most port.
I'm sailing on the Solstice on May 2nd also, I love the Solstice class of ship.
Looking forward to getting away, haven't been away since the Oasis last Dec.
