Another Christmas gift suggestion

I have a few close friends overseas whom i've not met in years. We only ever keep ourselves updated through emails and MSN. Just like me, they have kids and lead a very normal life. I make it a point to send their kids something each Christmas. I cant think of anything to send them this year. So, i bought them all Sea World Tickets instead. I heard my friend telling me what a wonderful time she had there with her family and how her kids love going there. I guess, my friends' kids will feel the same way too. Just want them to have a happy time this holiday.
