Is there an age restriction on renting hotel rooms in France? I know that in the States the sometimes give you trouble if you are not 21 years old.
It depends where you stay. Are you just talking about
Disneyland or Paris? I'm not sure about Disneyland, but you will be able to find a place to stay in Paris. How old are you exactly? If you're over 18, I'm sure it probably won't be a problem, but I'd confirm in advance when you make your reservation. You will be asked to show your passport when you check-in, so they will find out your true age.

US guests (or really informed Europeans): where is the best place to change currency? Should I do this before, in Paris, or in Disneyland -OR- should I just stick with my charge cards?? I have American Express and the Disney

Visa.
Use your charge card whenever possible. The American Express probably will not be accepted readily (I think, I may be wrong), but Visa, they're everywhere.

You may get a reaction to the fact that it's a Disney Visa when you're in Paris, but if you assure them that it's a regular Visa card, it'll be fine. In Disneyland, you will only need cash if you buy something at a food cart (same as in WDW). Your credit card (or your resort ID, since you're staying on-site) will be accepted in all shops & restaurants.
Try not to change currency if you don't have to. The rates are often very high, and you can lose quite a bit of money. I'd just withdraw cash from an ATM. Even with a 1 euro service charge, it's still the best deal, by far. Check to see if your ATM card will be accepted in France before you leave. If it has a certain logo on it (NYCE, Cirrus and others come to mind), it'll be fine. If you're uncertain, call your bank.
Definitely avoid changing currency at hotels and at tourist centers, as they'll take a huge chunk. If you must exchange currency, try to go to a place such as Thomas Cook, as the rates may not be as bad. Alternatively, you can get traveller's checks, of course, but those have their own set of pros and cons.
I would get some euro in cash before you leave, especially if you need to pay for your transportation from the airport in cash. I recommend a place like Thomas Cook or an American Express travel center.
