Yeah it's just psytrance, just like Glade.
Just looking at Ryanair now for flights and prices.
If you fly out on the Friday morning and come back on the Monday night the flights will cost you 77.15GBP.
Fly out on the Thursday night and come back on Tuesday morning you pay 72.15GBP. If you fly back on the Tuesday night (just incase you wanted to spend the day fucking about in Rome) then it will cost you about 59.15GBP. These prices all include taxes as well. Oh and I'm assuming here that you'd want to fly out from Stansted?
Now just say you want to get early bird tickets to Sonica. Well if you get the early bird 55 EURO ticket, then converting that to pounds it works out to be around about 38 pounds. Just say you took the cheapest options you'd have change from 100 pounds. Lets face it you'd probably spend the same amount on other things whichever one you go, but with Sonica you'll be going to the beautiful Italian countryside, possibly going somewhere you've never been before? Oh and the Italian partygoers I've met here are just absolutely nuts (in a good way).
