Both of my kids gave up their afternoon naps instead of the morning one. I would put them down at the normal morning time, in our case at 10:30 and then let them wake up on their own. Then they would breeze through the afternoon and be ready to sleep again at bed time. I know most kids give up their morning nap, but not so in my case and it might be the same with your little one.
What I did was just take a couple of weeks and not plan a whole lot. Once I knew for sure how much sleep my kids needed, it was easier to know, for example that an appt could be scheduled after 12:30 since they would be waking up from their nap around then. Just be patient. Your child will let you know what is working and what isn't.
Good luck.
