It's been years since we visited Bryce, but it is on our list for sooner rather than later. If your staying at Ruby's they used to have a Rodeo on a weekly schedule. It was fun. Years ago we did the walking thing down to the ruins with the ranger, that is no longer an option for either of us, but it is a large park with many historical sites, so a couple of days of touring could certainly be entertaining.
what ruins at Bryce? Are you sure you aren't thinking of Mesa Verde?
As for the original poster's question. If you aren't hiking, I would suggest at least day and a half at each - i.e. two nights stay at each. If you like sunrises and sunsets, that will give you time to catch each. Stargazing is nice too.
