I don't think there is a f/b gp for this trip yet. Jana is proberbly checking for us. She did say she would post the link as soon as one was started. May be you tried to join the Olivia travel group, that has been closed for ages cos had reached the maximum no of friends allowed ! soo popular. You can still be a fan of that gp tho and still see all the posts.
Hope we do get a f/b gp for this trip soon, reach more travelers than the connect gp, Jayne
