I used to go for longer trips before I had kids. Work is also an issue because if I took 2 weeks off from work I would NEVER get caught up. Since no one else can do my job, my work just piles up until I get back. I can barely leave the kids for a week let alone 2. As much as I need time away, 5 or 6 days is more than enough.
Now, before I had all these grown up responsibilities, I was there every 3-4 months or so. Mainly just because I could, and it is more fun in Jamaica than it is at home. lol.
