Quick glance at Ryanair website.
Departing Glasgow on Fri 18th June 10:30am, Retrurning to Glasgow on The 24th (Gives a day free in Gothenburg).
£240 from Glasgow-Gothenburg
£115 from Gothenburg-Glasgow (for some reason this flight has no taxes)
To put that in context, thats £355 return, for FIVE PEOPLE (not each, FIVE)
Giving us a grand total of £71 each. That is with ONE hold bag up to 15kg and carry on luggage (COMPUTERS).
If you can fit your computer and clothes into carry on baggage (unlikely but its up to you if you want to try it) then you can deduct THIRTY POUNDS from the cost of your flights.
Travel insurance is £14 each extra.
(God I love Ryanair)
That is also web check in being absolutely mandatory.
Just to start chucking some numbers out there. Next stage is from the airport to the LAN venue. And a hotel (Dreamhack sleeping room is renouned for being teh worst nights sleep you can possibly have, 10,000 people sharing communal sleeping space.......no thanks)
