The short answer is no, I don't have to take him with me. However, the only pet sitter option has no experiment with chams and I would much rather take him win me so I know he's getting the proper care. I'll be gone for a week and would know he's getting the correct care if with me.
I would be driving and could plug the basking light into my car to keep the temperature up if needed.
My main concern is that it's 80 and humid here... and in 18 hrs the climate would be blistering cold and dry.... once I reach my destination, he would have his normal setup until we pack up to drive back 7 days later.
Do I take the risk of an inexperienced sitter or take the risk of changing his environment twice in a week span with two 18hr car rides in between? (Not to mention my uncle really wants me to bring him with me so he can see him) haha
