How to say Christmas greetings in Cantonese?

I've got two friends at school who speak Cantonese and as they know I'm learning Mandarin anyway, it'd be nice if I could learn how to say it and write it in their Christmas Cards! ^.^

So how would you write this in Traditional Chinese: 

"Dear Yongfei

Merry Christmas and a Happy New Year! I hope you get all you wish for!

Love Emma"

And how would you say "Merry Christmas" in Cantonese? I'd be really grateful if someone could help me out please! ^.^
