race week is what most go for
but i know people who prefer practice week
are you wanting to buy a bike just to use for transport while over on holiday
or are you planning to race or keep the bike
there nothing to stop you buying a bike but the insurance might be more difficult
me personally i love it all but 2 weeks would be too much for me as i just cant spare the time away
good weather and nothing to get in your way and im sure the full 2 weeks would be good
