I'm not sure if I'm even excited, such big event will just be a big anoyance and farb fest.
Perhaps it will be funny to march Ligny > Waterloo and instead of sleep in the tent camp find some empty ditch under some group of trees. and make our own fun.
Build some shelter from available materials and enjoy.
Then the battle is the only thing to be there for anyway, it will be large, hopefully better than 5 years back, not with a huge field so even if you have 5000 people you cannot see them..
