On to the good news - that means we'll get more time in Burgundy and Bordeaux. We're going to spend 4 nights in each instead of 3 and we're going to spend Sunday travelling between the two so its really not much of a lost day (it also is an 8-9 hour train ride). While looking at the train schedules and really plotting out the actual itinerary, I was starting to stress how we'd have to fit in everything we want, so this will work out best anyway and give us more time in each region.
(sidenote:I'm actually not 100% sure our chosen Chateau Monlot has availability for all three nights - he hasn't responded yet- but that's ok, we'll deal with it. I'll keep you posted.)
In the meantime, I hit paydirt with a couple of Burgundy sites - the general Burgundy Tourism site and the Burgundy Wine Tourism site, which is most useful as it lets you search Domaines that also have rooms available. Oh, I was excited when I saw that!!!! I've already sent about 6 emails out asking about availability. Its about 3 in the afternoon there, hopefully they respond soon so I can finish my booking this week!!! Wish me luck!
