I guess "tight budget" is relative... I suppose I'm thinking closer to a couple of thousand (plus spending) rather than £6-7k (which I imagine is still at the modest end for a family trip.) Generally that you consider you did it cheaply and it was a success.
I've spotted flights totalling £1000 (3 of us, May) and wondering if it isn't a pipe dream after all.
Where did you go, what did you do?
