Based on the information on this thread I just logged in (and had to enter my e mail address) and was able to book dinner reservations but NOT excursions!
We are on the 1st May cruise, Navigator, Ft L. to Monte Carlo. I booked two evenings in Portofino, one for each segment.
When I tried to see what excursions were on offer I was told that they were not yet available but would be within 120 days of sailing!! Anyway I asked my travel agent to please book the ones I wanted some time ago so I assume this is done...really I was just curious about what was showing for our cruise. I think that the excursion booking part of the new website starts with the Mediterranean cruises after ours...
