OAT ----Halls stupidly expensive. So find rental property and pay for own meals and beer and get up early to get into OAT each morning blah blah blah in the rain.
FTE ----- all accomodation on site and paid for along with 3 squares a day. Only money required is for beer which at happy hour works out at 40p a pint. Or 1.50 Euro the rest of the time mmmmmmmmmmm. Oh and buying hi-lighters because you forgot to bring any with you.
Other wise the choice is totally upto personal preference.
C'est fin.
