Hi guys
Your best bet is to check
www.henrybevan.co.uk .... it contains a lot of useful information on amongst other things the essentials to bring with you.
Ryanair allow 15kg hold baggage and 5 kg hand luggage (I think) and seem to enforce it strictly.
My best advice would be to either fly Heathrow/Madrid/Jerez or look to flying to Seville from Heathrow. But - most of the people on my course did come on Ryanair but they've just got less stuff here than me!
Any other questions pls do ask.
PS - Bring a bathmat if possible as they are not supplied and are pretty neccessary to avoid flooding the bathroom!
