I am all in with the "take him with you" idea; Dez goes everywhere with me. For hotels, I have a large, clear plastic bin lined with paper towels, topped with a window screen, digital thermometer. The heat lamps go on top and are heavy enough to keep screen in place. I bring a roll of paper towels, bottled water, crickets, worms, veggies all cut and bagged, leash/harness--all his stuff--in a tote bag, along with extra extension chords, spare light bulbs. For a few days stay, I do not bring his big UVB flourescent fixture, but I make sure he gets out (on me, harness and leash on) in the sun every day. I also bring a heating pad, place it under half of his bin (so he can move on or off it) on low, to keep him warm at night. I adjust the heat up or down by using folded towels to cover screen, if needed. At hotels, I keep the "do not disturb sign" on door, so maids are not surprised! (I never let him run around on hotel carpets; never know what they have used for cleaning, or what he could find to eat.)
For day trips and car travel, he rides in a nice carrier for dogs that looks like a designer bag, with nylon netting on the ends for ventilation and looking out. For heat, I fill a plastic bottle with hot water, make sure it has no leakage, wrap it in a thin kitchen towel for him to stay warm. I like the pedialyte bottles; they are square, so do not roll around. I place some duct tape over open top, then screw down lid to make a good tight seal that will not leak hot water onto my baby. It stays warm for hours, and is easily reheated by refilling with hot water from a bathroom faucet. Dez loves his travel bag--he can see out, and feels safe. He loves car travel, and if my hubby is driving, Dez can ride on my lap or shoulder, but if I am driving he stays in his bag for safety sake. I like the fake designer dog carrier bag because I can take Dezi in with me, just about everywhere, and no one knows it is a Beardie in the bag. I cover the screen ends with a magazine, if I want to look like it is a big purse. Most people do not notice or ask.
I have friends who would look after Dez for me, but I know he would not eat well, and they would not see the more subtle signs if he should become sick or depressed...I also am picky about keeping an eye on his heat,humidity,poo,etc all throughout the day. So, where I go, He goes! ...Have lizard, will travel!
