Hi...
Ginlizzy.. Light shoes and trainers are OK, but sandals and flip flops would be better. We are extending who we give things to because of what we get (scarves, socks etc that aren't really suitable for Goa have been sent up to children in the Himilayas etc), we will accept anything really, but remember the chidlren are small (not british sizes) so aim for clothes for children under 13 years of age...
We haven't had confirmation that we can get it this year, but hoping we can. All the airlines were great last year, especially Mytravel when it came to allowing Charity Excess Baggage..
We have a form on our website which you can fill in, this is then sent to us and a month or two before you fly we'll then ask the airline for extra allowance. We have a lady called Mel who is looking after this for us, I'm trying to sort out a CWT email address for her, but will have to wait till I return to Goa. She will then get any extra details and contact you when she has been contacted by the airlines... We need at least a months notice before you fly to have the best chance, if you fill the form in ASAP then we've got your details and we will try our best to get the luggage allowance...
Here's the form....

Also on the web page is an idea of what to bring (at the bottom), this is just a guide as I can't think of everything.
