Release Date: When approved or after I'm back from vacation?

[worldalpha]

Well, I submitted my game app last Friday. I was hoping it would be up for this Friday, but I realize now that is wishful thinking. I'm going to be away on vacation come Saturday with limited Internet access for the next 3 weeks. My plan was to get it up and see how it goes and do a big marketing push at the end of the month.

Here are my questions:
1.) Should I launch it when it is approved, even if I'm not around, or should I wait until I get back?
2.) Will launching it with minimum "tech support" be an issue? I can fwd any tech support to the developers, to correct obvious bugs.
3.) Will doing initial promotion for a game 3 weeks after launch a bad idea?

Answers to the above will help me try to decide my launch date dilemma.
