Well, if I remember correctly, OP took some week-long private lessons in Hawaii, and he trains intensively, so he may be ready for more than the average newb.
Nonetheless, I agree with Ghost about the exotic locales being absolutely unnecessary. If OP has only surfed a total of 21 days, does it really make sense to go to Bali for a week? Or two?
I'd recommend something more amenable to beginners, whether it be in Centro, Mexico, or California. Then again, perhaps I am under-appreciating the value of private lessons on world class waves....
To afford Bali, but only for a week ... que lastima
The lessons in Hawaii were really good, but the ones in Costa Rica 2 months ago were far better. I think it's because the instructor was a considerably better surfer and the conditions were also much harder. That being said, of course it didn't make me a pro and I would never dream of paddling out in double overhead. However, a shoulder height wave would be perfect for me, crystal clear warm water would also be a nice plus.
Leaning towards Mexico or maybe even south shore Oahu, or maybe a different island.
If not for this thing called a career I'd be on a plane already....
