How soon is too soon to ask someone to hang out?

Anonymous
We've been talking online a little. He did imply he wanted to hang out with me this summer, I think. The subject hasn't been breached again though so I might bring it up and ask if he wants to hang out.

He's going on holiday for a week though, leaving on this Sunday. Should I ask if he wants to maybe do something tomorrow (which is really soon as we have only spoke online for a few days) or wait until he's back from his holiday?
