I am 90% sure that on Party you can withdraw any time after you complete the raked hand requirement. The only thing you will lose are your Party Points (the 1000 bonus points for making a deposit). Those don't generally get credited until about 2 weeks after you make the deposit.

Now as far as the initial deposit itself, if you've made a cashout during the bonus period you aren't eligible. So, if they say "make a deposit between Aug 5 - 10th and get 20% bonus", and you make a cashout on Aug 5th, then a deposit on Aug 7th, you won't get the bonus.
