RP from 05B - please help me with reception card info so I can order my invites!

I want to write this:

Adult Reception, Dinner and Dance
half past six in the evening
Jericho Terrace
Mineola, New York

My questions are:
1) do I capitalize the 'h' in 'half past...'
2) do I write out the address for JT?

Thanks!
