Neither of mine napped well. DS8 gave up naps entirely and was sleeping 11-12 hours per night by 30 months. He gave up the morning nap at 11 months.
DS6 was roughly the same, maybe a little earlier to give up naps.
It's exhausting when they are little and you're trying to fill the time. I had both kids in a Mother's Day Out program at a local church for 2 days a week from 9-2 just to get some downtime for myself.
We also did story time at the library (there were 2 libraries close enough that did different days), swimming lessons, park play dates with a neighborhood group, Pump it Up, Gymboree play and learn classes, gymnastics, soccertots, and basketball for toddlers, not all at the same time of course, but those are some ideas.
Sadly, I was not successful at enforcing an hour long quiet time, but it worked for some of my friends.
