Hi,
I looked through some past postings about visiting Versailles, as well as Rick's page on it, and I still have a few questions.
I am planning on leaving early to visit the chateau, then renting bikes and riding around the grounds for a little while, maybe eating some previously-bought picnic supplies while in the gardens. I don't plan on visiting the hamlet since I think I'll spend my time better returning to Paris and seeing some sights in the afternoon/evening, and I probably won't go on a weekend to see the fountains (to better avoid the crowds).
I think I am going to purchase the combo RER/chateau entry ticket at the RER station, it looks like it saves a few Euros and will let me bypass the ticket purchase line at the chateau. Is this worthwhile? I think it won't get me into the gardens on fountain days, should I decide to go then.
Also, I noticed there is a checkroom for large bags when you are going on the chateau tour; around what size is not allowed? I am planning on bringing a small-ish backpack almost everywhere when I travel around Paris, is this going to be a problem at any sites? I am going to visit most of the "touristy" places, but in general is a backpack going to be an issue anywhere as far as rules about bringing it inside? Eiffel Tower, Louvre, Arc de Triomphe, Notre-Dame, etc.
This is the bag I am planning on taking, if it helps:

(I'm also trying to take this on the plane as my "personal item" carry on, I hope that works!)
Thanks for your help, sorry for writing half a book!
