Around what time do early entry tickets go on sale?
-I dont really know but I'm going to assume late March/early April

What day is the busiest?
-Saturday by far. If you're cosplaying, don;t wear something fragile or that trails on the floor. And don't go barefoot (from experience, IT WAS NASTY)

Do many people attend the Friday?
-Again, not sure sorry!

Glomping - Myth or Reality. Does it still happen? (I kinda have some back problems due to a neck condition, and from personal experience whenever my best friend glomps me, it hurts for a few days after -.- So I'd like to avoid it if possible ^^"
-I've seen less glomping of strangers in the past few years. I think people are slowly cottoning onto that a)people generally don;t like it and b)they could legitimately get done for (attempted) assault. I've not been glomped in a long time myself, but a lot of people do come up and ask for hugs. If you don;t want a hug, don't be afraid to say no!

Are the items for sale fairly pricey? How much moolah does one take to satisfy one's inner geek/otaku?
-It depends on the item. A lot of things are quite pricey, but some of the dealers are willing to haggle a little (like say, £15 instead of £17). Sometimes you can be really lucky and find an item cheaply. Yesterday I got a figurine for £5 that sometimes goes for about £15 online. Shop around a little and try your luck at haggling a bit. I take about £50 on average and usually don;t spend it all.

Do you, personally, spend the whole day at the Excel center? Or do you go off and find other attractions...?
-I usually spend the whole day there. I do go outside of the main hall a lot to get air/cool down. I love sitting in one of the bays at London expo and watching all the cosplayers go by. I find it;s the best way to bump into someone you know!

Have lots of fun at your first expo!

Around what time do early entry tickets go on sale?
A few months before the con, but generally if you can hold off till after one the tickets go a few pounds cheaper on the day ;D

What day is the busiest?
Saturday for defo but then again watch out on sunday's too as prices go down, everyone loves a bargin ;D

Do many people attend the Friday?
A good few hundred I would say, people like to check the event out and see where everything is located.

Glomping - Myth or Reality.
I'd say a bit of both, people are more tame now. They will run up and ask to hug you but some noobs don't respect the boundary.

Quite, you can try to bargin and haggle with them, some buyers will drop prices especially on a Sunday for the last minute sells. But some just don't move, tried three stalls for the same item in the last half an hour, they would not move a £30 plushie down to £25 for NO MAN.

I spend all weekend there. Not inside because it gets really hot, but the grassy areas are nice... if you can find a place xD

Been going since 2009 ;D

Thanks for the tips!

Yeah, I would really HIGHLY recommend early entry tickets. Even then, you'll probably have to queue for a while, but the queue for normal-entry is just insane and wastes most of the day.
