pokerstars: to deposit or not to deposit, that is the question???

[lillumultipass]

hello everyone!
As I said in another thread, I have just deposited on Party, but I was also considering depositing on PS to benefit from the reload...but, at the moment I am writing, I have also logged on at PS, and there are around 7000 players, but when I look at 1/2 Limit (what I play most)I only see something like 6 tables (10 max) that are full and around 7 6-max...which is not that much for a big site...Thus, I am wondering if in fact most PS players are mainly playing in tournaments...Moreover the bonus does not seem to be that easy to clear, am I wrong???
Also, as I have to clear the party bonus, I might not have time to do both...although now that I think of it, I think I have read that PS's bonus does not expire...
