MicheleM,
I have to say I have never had an issue with luggage with CC. The guides are great about schlepping it for you, so I try to pack light anyway. I usually have 2 bags, a checked and carry-on, and that's worked well for me, especially if you put all the bike gear in the the checked.

Re: how much leisure time is built in to the tour? There might be a cultural stop or two on a day, and then when riding there's usually a few re-groups and a lunch stop. Other than that it's your own pace, you don't need to stay huddled as a pack, and you can stop and photograph/shop, etc. as you wish. As a courtesy let the guides know your intentions so they don't worry about you, or so they can worry about you. Taking the day off, or part of a day, is truly cool if that's what you chose.

Re: Did you use the hybrid or the road bike? I've done both. Started with the hybrid when I wasn't comfy on the new fangled road bikes, then switched once I got my own Bianchi. Love the Bianchis they provide. Day 1 is all about getting you fit to your bike and they're great about helping you adjust things through the course of the trip.
