They actually look pretty good.
I have just had a look and perhaps wouldn't mind the September one.
Do you guys know, if I chose the fund raising option, how much goes to a charity, I assume £1000, and which charity is it?
Thanks.
You can choose your own charity. The self funding option is £620 plus the £149 registration fee. With this option I think it is up to you then to contact your chosen charity and arrange sponsorship. The £620 is therefore the cost of the trip.
The sponsored option costs£1240(minimum amount of sponsorship and of this £620 (half of it) goes towards the cost of the trip. The remainder (minimum of £620 depending on how much sponsorship you raised above the £1240) goes towards your chosen charity. These are the figures from AcrosstheDivide
GlobalAdventureChallenges figures are slightly different. 1. £650 self funding and 2. £1650 minimum sponsorship option. With this £1000 (as you said) minimum would go to your chosen charity. Plus, of course, the £149 registration fee.
I am tempted towards GAC because the information they provide is in more detail and better presented than AtD.
Also, DiddlyDodds has positive comments about them.
