I would say do whatever feels best to you. At that age, I wasn't willing to plan anything on a specific schedule precisely because nothing was working well yet with naps and nights, I was exhausted, and it was just too stressful for me. I wouldn't have enjoyed it. And its not like they need that type of activity at that age.
But if you think you can enjoy it and not worry too much, then I would say to go for it. It is nice to be out with other people. I know that was the age I started to get depressed, probably partially from so little contact with anyone else all day except a non-sleeping baby. But I just tried to go places that I could go whenever and not have to plan ahead of time.
