It's so exciting to hear that your trip is right around the corner!
About finding accommodations, my thought would be that during the main season, I'd advise booking accommodations in advance, as there is high demand. This isn't to say that there might not be B&B's available in the area to take last-minute guests, but in addition to just being a bit on the safer side, booking in advance would give you and your husband more time to enjoy your adventure without having to worry about where you'll be resting for the evening.
As for staying in a castle, I understand your view perfectly! There is something absolutely unforgettable about staying in a classic castle, complete with exposed stone. There are a number of options available to you to help make this dream come true. You could use our Accommodations Finder
to find your dream castle, and as a bonus, it's also useful for finding B&B's. I've already sorted by castle stays, and you can look through to find your fantasy retreat.
There's also a helpful article right on our website all about castle accommodations
. I'd recommend taking a look at The Black Castle
, which has an old-world charm right out of a fantasy novel.
I do hope that this helps!
