Thank you very much. I do appreciate your input. I also like the idea of going with travel agency, but not sure if they would ever accept little babies on their bus, and also afraid their schedule is too tight for us. Anyway I will certainly call them to ask. Even if I do decide to drive, I won't make a tight schedule, we may only go one place in a whole day (avoiding rush hours) and may even spend one or two days nearby hotel. Anyway I really appreciate your words, the care you pay to someone you never know and never meet on the web. Thanks again.
