Hmmmm. Forty plus years ago we started with a week and quickly expanded to ten days. And with the advent of our four timeshare weeks we now go for two weeks plus twice a year.
So to answer the original question, I can only say the answer has got to be in excess of five weeks, or so it seems to me...... but ask DH and he'll tell you anything more than ten days is too much for him. <img src="http://www.traveltalkonline.com/forums/images/graemlins/jester.gif" alt="" /> <img src="http://www.traveltalkonline.com/forums/images/graemlins/jester.gif" alt="" />
