We used Sighteeing Roma for HOHO bus tour around Rome. 2 routes to choose from and 2 routes all included in the 1 price of €20. The ticket is also valid for 2 days. We saw at least 6 or 7 other companys doing the same thing, the 110 bus seeming to be the most frequent. On our way back to port now for a 7.00 sailaway. Its been a very busy 2 days and we now have almost 2 sea days to recover. Sent from my BlackBerry® wireless device
