Yes, it will be pretty expensive, but the investment is worth it. One hidden cost I do know is the USA Hockey Registration, which is roughly $35.
Here is the link for the USA Hockey Registration:

Here is the link for the youth leagues for the Aliso Viejo rink:

I don't have time to break the costs down right now but I'll do it when I get home tonight.
