For me it has to be Halloween Hands down. Not just because it was host of some very difficult/tedious achievements (which I'm quite fond of) but also the amazing decor that the world in which I spend much of my time in is laced in. This year's two new amazing companion pets also helps.... heaps.

Brewfest without a doubt!The ram racing and the mug throwing contests are some of the best fun you can have with your friends!Besides, being drunk makes it all alot funnier.
My favourite would definitely be Brewfest.
Children's Week, for everything but the PvP achievements. I love helping out my little orphan though.
Brewfest.Getting completely smashed.Fending off Coren Direbrew's cronies.Obtaining the mighty Brewfest Kodo.Discovering mystical pink elephants.Taming a wild wolpertinger as your companion.Wearing beer goggles that make everyone a (very sexy) gnome.Transporting beer on a ram while having some kind of kinky party where I whip the ram and he eats apples most likely laced with cocaine.Gotta' love it.
Hallow's End because of all the costumes and fun items. And of course this is the holiday which celebrates the escape of Forsaken from The Lich King's icy grip and regaining their own will.
I'd have to say winterveil, main reason being when I first started, waaay back in vanilla heh, had no idea what I was doing.my computer did not handle being in the major cities well, and along comes winterveil, lag city -_-' took me three days to be able to even be able to talk to old man father winter lol. Finding Santa (father winter) in Ironforge was a blast though as I had no idea that there were any holiday modifications so it was fantastic.
I love Pilgrim's Bounty. Great time to max my cooking on all the toons :D
Lunar Festival! It's awesome, there's dim sums and an amazing ambiance surrounding the whole event. Also it's going to be even better once Mists of Pandaria comes out!
My favorite holiday in Azoroth is the Feast of Winter Veil, such a beautiful time with free gifts, not to mention throwing snowballs at people ---O ^_^!
fave one has to be the fire festivalbecause I love using the Brazier and click on the pole to have a spinning flaming draeneialso got a whole bunch of people to copy me which resulted in a flaming sea of spinning flaming draenei and with enough people the pole caught on fire too so it was just magnificent
