We are booked as well! My name is Andrea and my husband and I are celebrating our 10th anniversary. We have another couple traveling with us and we are so excited, since this will be our first cruise.
If anyone is interested in sharing excursions, I have booked tours with "Rome in Limo" in Rome, as well as Florence/Pisa. We are a group of 4 (2 couples) in our mid-thirties and have another couple joining us (age 55+) that we met on the cruise critic roll call. We need another 2 people to join us, giving a total of 8. Because I booked two tours with them, Rome in Limo is discounting each tour to E550, or E68.75 per person, not including lunch, entrance fees to museums and sites, or gratuities to the driver. I have heard nothing but positive things about Rome in Limo, and you can read some rave reviews on tripadvisor.
My group of 4 has decided to get a hotel and stay overnight in Rome, but the driver is still taking the other couple back to the port. So you could do either, and they're fine with that.
