So here's the experience in case you were wondering:
FONTAINEBLEAU & VAUX LE VICOMTE- Tour
Here's how it works:
Book your tickets online. You'll get your confirmation and voucher to print. In my case I couldn't print anything that easily and was concerned about how they handled it.
I contacted them 3xs by email, but no response.
I find a internet cafe (remember those?) and print the 2 pages for 2euros.
I show up an hour early and present my voucher, they give me a bus ticket and tell me which bus to line up for 15 minutes ahead of time.
In the end I guess I could have just shown them the email and they would have given me a ticket anyway...so don't sweat it if your AirBnb doesn't have a printer.
There are two bathrooms in the offices. One is out of order. So go before you get on the bus.
We turned our ticket over to the person who gives us our CHATEAU TICKETS and WHEN TO MEET DIRECTIONS. She speaks several languages.
The driver was quite jovial and friendly. Really enjoyed his attitude throughout the trip.
The bus has CELLPHONE CHARGERS at each seat. The seats are a bit tight for those with long legs.
The bus has a toilet those I didn't see anyone use it.
The first leg is to Vaux le Vicomte, it's out in the countryside. It's great because it took maybe 35-45 minutes to get there and it's not busy at all. Your guidebooks will tell you all about the place. Me, I preferred Fontainebleau it as well as Versaille. There are several bathrooms there and we had 3 hours to kill.
I ate my lunch that I brought with me in a peaceful side garden.
Everyone meets back at the spot the driver said and we're off to Fontainebleu.
Fontainebleu has a town that has sprung up around the chateau. There are a lot of places to eat, boulangerie's patisseries, etc. Check them out. The driver tells us where to meet and we're off.
The chateau tour is more diverse and ostentatious as everything else is.
The gardens are close to the the manmade lake and are excellent for picnics...hence, get some food or whatever and plan on relaxing there.
There are several bathrooms throughout, but the one behind the chateau that looks open to the public is .30euros. Inside is free.
We meet back at the bus and we're heading back to Paris. If it's a weekday, it's going to be thick with traffic. SO BE PREPARED. HAVE FOOD AND WATER...because it took 2.5 hours to get back! That's just the way it is.
Otherwise, the air-conditioning on the bus can get a little chilly even with the top vents closed. BRING SOMETHING TO COVER YOURSELF WITH.
The service was reasonable and I didn't expect anything more than a ride to and from the spots. And they delivered on the most basic things.
