I managed to catch a cold. So far, it's a medium-mild sore throat. So maybe half my exhaustion isn't so much jet lag as cold-catchingness. In any case, my innkeeper's mother and sister gave me menthol drops and found me an apotheke open on Sundays, and I'm going to take it pretty easy today, writing and resting and studying enough German to have a nice dinner somewhere tonight.
I extended my stay in Bingen for two days, and am ditching Aachen. Aachen was a nice idea (thermal springs! Charlemagne!) but realistically, it was already going to be a haul to get up there and then back down to Rothenburg ob der Tauber two days later, and my book probably isn't going to go there anyway. (People in my book go there, but off screen, so. Thin thread at best.) Rothenburg is a "medieval paradise," and on my way to Munich, which is where I catch my flight to Romania. So it's still on the list.
There's so much to see in the Rhine valley, I will embrace another two days, and the hoteliers here are just fantastic. The owner's little sister is K's age, and a voracious YA fantasy reader, so we chatted books after breakfast. In the meantime, I will be able to catch that lunch at the Hildegard Forum, and get to all of Hildegard's sites, including looking up her reliquary. And hopefully, manage to keep this cold as low-grade as possible.
