Some questions
 

I'll be taking the bus to the next expo and it's about a 1 hour drive (Brampton to Mississauga). Would a leo be okay to travel that far? Would I need a heat pack or would it be hot enough outside? Would it be okay in the container provided or should I bring something else? If I end up buying mealies as well, would they be okay?

Also, what kind of tape can I use to stick my UTH to the tank. I read something about foil tape a while back, but can't find where I read it.

The gecko and worms should be fine for an hour in whateever container you get them in. They'll be fine at whatever temperature you're comfortable with in the car.

Its in the bus. If its Summer there they should be good but if your concerned it will be chilly bring a heat pack. The Mealies will be A OK.

Yea it should be fine aslong as your careful with the container the leo is in.
