Thanks for the quick responses.

The hotels Ryumeikan and Granbelle have only single rooms for my date and getting two rooms would be about 20,000 Yen, but Villa Fontaine Uemo does have doubles/twins for two people for 8100-9600 and looks very nice. May be just the thing I've been looking for.

Will check out Kamakura in the morning. And the Yubisashi map from White Rabbit Express. Couldn't see how to order it, but I'm sure there's a way.

Any other ideas, suggestions more than welcome.
