yeah I think Cider has a different meaning in the US. Over here it's definitely alcoholic.
Try Magners, it's pretty drinkable (although personally I prefer the, ahem, stronger stuff):

Alcopops were popular in the UK in the 90s (showing my age here) - stuff like Hooch or Two Dogs alcoholic lemonade, Bacardi Breezer etc. They're usually just vodka with fruit juice and half a ton of sugar to take away the alcohol taste

Vodka hasn't got much flavour so I suppose you could make a fruit punch with a couple of bottles of vodka and some orange juice...
oh and you'll need plenty of beer for the blokes. Doesn't matter what type, we tend not to care after about three or four...
