My hubby was one of those people who wouldn't go for a week, his argument was that the flight costs the same and the second week wasn't much more.
I have managed to 'drag' him away for the odd week here and there, including having a quick week in Benidorm from the 28th April this year for his birthday.
We've done 7 days, 10 days, 11 days, 14 days, 5 weeks, 7 weeks (OZ) and 8 weeks ( mostly in Spain)
Apart from the finances, various circumstances have in the past dictated the duration of the holiday.EG: work, kids in school, being a career for elderly parents and having the cat for the last 20 years.
Now, we can go where we like and whenever we like, so I wouldn't rule out any duration or destination while ever we can afford it and have reasonably good health, and even my OH has finally come around to this way of thinking.

Many of you know from my website and another place, that I had a cat called Sanji, sadly she died last Wednesday night. If you want to reply, please reply by pm so this topic doesn't go off topic and about me....I'm still fragile.
