Question for NYC heads

A group of people and I are trying to plan a trip to NYC this weekend. I've been a few times but we wanted to go during the Christmas season to see all the cool things they have set up. We were planning on going to rockafeller center to see the tree, probably bryant park to check out some ice skating , I read its cheaper than rockafeller. I'm not sure where but I've seen giant Christmas tree light bulbs and maybe giant toys set up too. Central Park will probably be a cool place to go to for the Christmas atmosphere.

Anyway my question is , do you have any recommendations we should go check out?
