Just a €9 bus ride from Garmisch, left 7:50, had a quick breakfast at the hotel before I left. Transfer from 9606 to 73 at Bad Bayetsoien (Echelsbacher Brucke). Pass thru Obergammerau & Untergammerau on the way. Frost covered fields of cows and goats, fog shrouded valleys. Part of Romantic Road. Arrived in Fuessen, drop off my stuff. I booked the hotel based on price and availability: I stayed at the Altstadthotel zum Hechten (which has the Ritterstub’n restaurant attached). Again, this was a “place for my stuff and to sleep” home base.
Get reserved tickets for the Castles. You’ll do Hohenschwangau first, then two hours later Neuschwanstein. If you miss your appointed time, you can’t get in. With reservations, you’ll still have to pick up your tickets so make sure to allow enough time for that (30 minutes before the first one, 60 minutes before the second one).
From the bottom, the best way to go is taking a one-way bus up to Mary’s Bridge for the money shot view of the castle, which then has a 10-minute downhill walk to the Neuschwanstein entrance. Then catch a horse carriage from the castle down to the parking lot (or walk, which I did – it’s a long walk, but downhill).
I took a nap when I got back but overslept, and by the time I woke up, most of the restaurants were already closed, so I ate at the restaurant attached to the hotel (cash only).
