edit: Not 'Have Keg,..' but 'There and Back Again'

Don't remember exacty, but it also depends on server lag. if you got a bit of lagg the animal will get exhausted before the buff fades.

As always. Buy the set for disturbing the peace. Do the Achievement, then tun the set back in again for tickets to spend on Brew of the Month and save yourself a bunch of tickets. That should cut down a lot of it.

I believe that you can get 10 to 16 on the daily where you must retrieve kegs from the caravan depending on how fast you are, 15 from doing the "Barking" daily and 10 from defending against the Dark Iron attack. So you can get a max of 41 per day. Plus you get 40 tokens from doing the non-repeatable quest to kill Coren the first time.

In addition if you buy your three pieces of clothing to get the achievement in Dalaran and don't care about keeping them as keepsakes, you can sell them back within the 2 hour time limit to get a refund on your tokens and then buy the Brew of the Month Membership. That means you only need to get 350 tokens in total instead of 550.

Sorry for the repeat of info, I didn't see Tom's comment about returning the clothes.
