Im going to disneyworld at the end of July. I have someone that is good with gliders and I trust, and know will take care of them. I'll my babies think I left them, its for a week and a half
People go on vacation all the time. As long as you have someone you trust things should be fine. You may have some kissing up to do when you get back but after not seeing them for so long I'm sure it won't be an issue.
I'm gone for weekends ALL the time and usually for 2 weeks at some point during the year. I'll be gone for 10 days starting next Friday. They've been fine for 5 years and no, they don't forget you.
