They don't appear to have a web site, Sara, which is unusual, unless I am not searching correctly.
Only looked for it, 'cause this is how we found out Grandaughter should have been back after Easter Hols the next day, when she carelessly thought they didn't
Thanks mickmc, but even though it says when they break up, it doesn't actually say when they go back. Shall have to send myself a reminder to phone sooner rather than later.
Finally rang up Tinkerbelle and for year 11s it is Tuesday 5th September. I used the link mickmc gave and sent them an e-mail asking, but so far no reply. Probably a good job i rang up.
