We have also been looking into a transatlantic cruise. Unfortunately, we started to make plans too late and my DH needs more lead time to take 3 weeks off: two weeks for the cruise and another week in Europe. The
DCL Magic TA looks amazing! I've always wanted to visit Halifax. I've been to Scotland and the landscape looks very similar. I also want to visit Ireland. But ... that cruise is totally out of my price range.
I think we'll probably end up with a TA next spring on Royal or Norwegian. The pricing is pretty close between RCCL and NCL "Sail Away" pricing and then adding the free drinks package costs only $20-$40 more per person per day and with sooooo many sea days I would come out ahead while the regularly priced drink packages don't even come close to breaking even. I had been pricing this spring until my DH told me that he couldn't take that much time off and we could be on a TA from Tampa to Barcelona on Rhapsody of the Seas for about $1600 for 14 days in May for BOTH of us in an outside cabin. It was $2300 on the NCL Jade for 13 days in April with free drinks and specialty dining. I'm sure that prices have changed a bit since I stopped tracking

. In any case, I'm looking at Spring 2019 now and I think that we'll go south to Italy instead of London. We've never been to Spain or Italy so I'd probably be able to visit both on the same trip.
BTW, we went to China in 2007 and it was AMAZING. We are not "tour" people so we did everything ourselves. We visited Hong Kong (and
Disneyland), Beijing, then off to Japan and Osaka, Kyoto, Hiroshima, Yokohama and Toyko Disneyland. We saw a lot in China on our own but I do regret not having the time to see the terracotta warriors in Xi'an.
ETA: In the meantime, we're looking at a 5-7 day Carnival or RCCL cruise in April. I'm a last minute planner when it comes to most of my cruising

. So, that's why I'm posting and reading on the thread.
