Since my time is so limited I am wondering what the best way to see some sights would be---I don't want to be crazy running around or spend a lot of $$$. I think I am willing to forgo visiting the Vatican/Sistine again as I don't want to deal with feeling like cattle in the crowds but maybe should see the Colloseum--I have been reading on here that I need to reserve tickets ahead of time?
Should I look into doing one of those hop on & hop off buses? Tour guide for a day (if so, any recommends for a cheap one---tall, dark & handsome would be a plus)? Just wing it on my own? I am staying at the Marriott Grand HOtel Flora on Via Veneto.
I am sure this question has been asked 100 times on her but search feature fails me. Thanks!
