Thank you so much for all the helpful advice. You've sold me on taking the train. I've travelled by train fairly extensively in Ireland and the UK and loved it. I'm sure Brian will, too. I was really only considering renting a car for our days in Belgium, but it seems that everyone agrees that it's likely not worth the trouble. No way would we drive in Paris. I'd die of a heartattack for sure.
Papaver, you're making Gent sound VERY attractive. I did a few searches on the other cycling site I frequent and several people on that forum said they prefer Gent to Bruges as well. I'll share all of this with Brian. In the meantime, if you want to forward your B&B recommendation to me, that would be great.
I'm sure to have other questions at some point!
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
