My opinion...not enuff savings to lock in 10 years....too many variables in life to lock in that long....if the savings were big enuff where u could miss a year or so and still be a good deal, then yeah....what if sickness in yur family or work or whatever gets in the way of your traveling in one of those years...and then there is the fact that we have been 4 times, have not stayed at the same place twice, and have not been on the same weeks twice.....hard to lock in 10 years of my life....
has pros and cons....
