If there is a way you can travel with your gliders, that is usually a good idea. I've done both and can promise they will be at LEAST mildly stressed out either way.
However, make sure they have plenty of treats and love while you are gone. I've only ever sent my sugar gliders to one person to be cared for. This gives them the opportunity to remember his scent from visit to visit.
I leave some of my clothes/Sugar glider hoodies with my friend every time I go so that they can be loved with my scent around to lessen their stress levels.
My biggest worry with my sugar gliders is weight fluctuation when I travel, if they get stressed out they can lose weight rather rapidly. So ensuring their treats and food is always ESPECIALLY delicious for them is usually a very good idea.
I don't think it's too much travel. Just try to recreate home wherever they go :D
