Thanks! We will be stopping in California from Hawaii before going back to Ohio. We definitely want to do the library and are planning a whole day there, possibly dinner in the restaurant to see the sunset, and then we will have another day and a half for which we have no idea what we want to do...hence the Ventura Marriott idea. I guess I will have to decide the rest of our itinery. We have only been to San diego on a previous trip and don't know too much about the area around the library.
The Reagan Library is a great place to visit. Probably the best Presidential Library I have ever been to. I went there when I had a couple of free days during a trip, but stayed at the LAX Renaissance because it fit well with my flight plan and was close to the rental car places (walking distance). I visited the Reagan Library day one and the Nixon Library in Yorba Linda the next day. Didn't pay at the hotel to park the rental because I could leave it at the rental car lot it was so close to the hotel. I'm glad I made it to both as they were really enjoyable. Such a history lesson in both!
Enjoy the trip!
