Tom is right; it really depends on the base. The main differences you will have between bases are shattered or CB, jump spell or wall breakers, and 2 (rarely), 3, or 4 hounds.
I wouldn't attempt a GoLaLoon with fewer than 4 wizards, but it could theoretically be done with 2 if the base allowed.
I also wouldn't attempt one with fewer than 14 balloons.
Then again, why should you take advice from me? I failed GoLaLoon every attack 12 straight wars. If it makes you feel better, I did come close to 3 starring multiple times.
