Yeah, my husband was pretty nice to do all that! If this were my situation, I would beg your husband to help you out... The frogs would not be happy to be moved.
If you have the timer, fogger, and hygrotherm already, then he really doesn't have to do a whole lot. Dump some crickets in maybe 3 times, change the water bowl, and make sure the fogger has water. You could have the de-chlorinated water in a gallon ready to go, and the distilled for the fogger in easy access.
If you're gonna take them along with you, I would bring your thermometer and hygrometer as well. Maybe not put the climbing stuff in the tank until you get to your hotel/lodge? I do not have red-eyes, only white's. My understanding is that red-eyes are very easily stressed. My first choice would be to leave them aat home. Your husband can handle a little bit of frog maintenance, expecially if there is some sort of prize when you get back home
