My daughter would wake up from naps really cranky and I wanted to be able to tell her to just get up when she was ready. I thought that if she was in a toddler bed it would be easier. I was right!
She was a little bit older than 2 (about 26 months) when we made the switch. She really didn't give us a hard time.
When she was getting ready to phase out her nap, she would stay up talking and reading books. It was more like a quiet time for her in her room, which was fine too.
Only one time at bedtime did she get up and come out of her room. With a serious warning, she got right back in bed and hasn't done it since.
It's definitely important for children to get enough sleep or they are cranky and hard to deal with. Best of luck!
