I am experiencing the same thing. I usually go once a year if possible. I went November 2015, and then got a chance to go a couple of days with some friends in February 2016. My next trip is supposed to be November 2017 but really I have been ready to go back since probably June. My friend went for her dad's birthday present just this week and I was sorely tempted to stow away in one of their suitcases! Not sure how I'm going to make it until November 2017 as that is more than a year from now. Ugh. I would love to be able to go every 6 months but I dont see that happening...
