I just double checked and we're doing 2 nights at the Hyatt Regency (Regency Exec King Suite) and then 3 nights at Hiiragiya for a total of 5 nights in Kyoto. We're staying in ryokan before and after throughout our trip as well, so I wanted to have a break inbetween and also to experience the Hyatt which looks superb. I can understand the hesitation about spending multiple nights on a futon but I've actually read that they're quite comfortable and it's part of the overall experience for me. Our room is incredibly spacious and open with traditional antique furnishings and magnificent views out to the gardens. It's a model of Japanese aesthetic:



I believe there are Western rooms with regular beds that you can book, though once you're going that route, a hotel probably makes more sense. I doubt the level of service can be matched anywhere though, at least from what I've read. That's also part of the ryokan experience. Admittedly, we're sort of using the Hiiragiya as a very expensive and indulgent 'crash pad' for several nights while touring Kyoto. We're only dining in on the night of our arrival, though I look forward to breakfasts and tea in the early morning sunlight overlooking the gardens.
