Oh dear I’m sorry to hear this! I didn’t book anything through RC because I was already late in the game and I think we are both on the same cruise! I ended up booking a tour thru Tripadvisor, went with one that had decent reviews and keeping my fingers crossed that it’ll all work out. We’re also doing Rome and Florence on our own taking trains but will make sure to leave in ample amount of time and not leave it too close to ship’s departure time. So hopefully it works out. Honestly the RC excursions are waaaaay too expensive and I haven’t heard amazing things about them either from other passengers. I did book some “skip the line” tickets for Vatican and Accademia thru tour operators just cuz everything is sold out thru the official websites, but that’s my mistake for not getting ahead of the game. So we’ll try to make the best of it. I’m a nervous traveller like you but just trying to go with the flow at this point.
