Trip to Egypt?

Hi,

Coming back to the expensive or not so expensive trip to Egypt to 
visit Bill by the Weasleys in the summer before year 3.

While rereading CoS (as anyone here in anticipation for book 5) I 
noticed that the Weasleys also visited Bill during the Chistmas break 
and even intended to bring at least some of the kids.  It says in the 
book (no exact quote) that "Fred and George decided to stay at 
Hogwarts for the Christmas break instead of joining their parents in 
visiting Bill in Egypt".

Now, if the trip was that expensive that they could only do it 
because of the money they won, how did they manage to visit him over 
Christmas and originally plan to bring the twins as well?

Any thoughts?

My 2 cts,

Vicky
