Weening 10 week old from swing!

When my baby girl was born she slept so good in her crib for the first 3-4 weeks. Then out of nowhere she wouldn't sleep more then 15-30 min in her crib. She however loves her swing and will have 2-3 hour naps in it during the day and sleeps 5-6 hour stretches at night. I moved the swing to our room beside my bed so I could watch her but I want to break this bad habit asap! Sooo.. Tonight I set up the playpen beside my bed. I rolled towels and put them under the sheet in a little square so she doesn't feel like she is in an open area. Anyone have any more ideas that helped make the transition easier? My last baby slept in the swing until he was 6 months old and I cannot have that again! I have a feeling there won't be much sleep tonight lol.
