Yea, go alone. There are soooo many people going to be there that you wont even feel lonely. You'll be lost in the crowd
I went with my BF last year (he isn't vegan) and it was awesome. I can't wait to go again!!
Even if you just pop in for a quick lap.. there are so many good stalls and you can get samples and good prices on some awesome vegan stuff. I already have a small shopping list of things I want to try out, weee!!!
Oh and I dunno about this year, but last year.... there was just... so many food stalls for lunch.... I wish I could have stayed there long enough to counst as breakfast lunch and dinner so I could have tried something from everywhere!! It all looked fantastic!! It was just so lovely being able to pick from ANYTHING on the menu for once!!!!
.. I'm well excited!!!
