We have the tv on here in the mornings too but once Play School is finished its turned off.

We don't do planned activities as such - except going to the park - but just do whatever DD#1 wants to do. She has a basket of toys and other stuff left around the family room so we'll play with blocks, read books, play with Night Garden stuff (yep, she's got just about everything there is thanks to her Grandma). Playing chasey is also a hugely fun game - I carry DD#2 and we chase DD#1. We also spend a lot of time outside in the garden when its a nice day. She also plays really well on her own and is starting to do a lot of the stuff Sangie was saying - feeding bears/dolls and tucking them in.

Just wait for another couple of months though - if your kids are anything like mine they'll start playing together and you'll struggle to get into the game sometimes!!
