We have always booked on the cruise line, but one of these days we are going to get brave and try SonnyV's method.
To answer your question lola-1, we are cruising November 25th and they still don't have excursions available for two of our ports. I tried to access the excursion site yesterday and the message said that the site was being updated. My experience with RCCL is that this updating can last a long time! You just need to keep checking back. On our last cruise, we had to purchase the excursions on the ship because the site was down for a couple of weeks. Hopefully between now and October it will be working!!! We love RCCL, but I do think their website is less than perfect. It's still our favorite line. Enjoy your cruise!
