While I agree 100% that you want to let the brew age in the bottles for a few weeks to help develop the flavors, I don't think leaving it the primary for 3-4 weeks is really needed. I've found that aging is aging, in the bucket or in the bottle. Unless you have a lot of particulate floating around, a secondary is not a necessary step. Especially if you are doing extract and specialty grains. It just complicates your process.
Throw a couple six packs in the closet, or under the house and let them mellow for a couple weeks. You will notice a definite difference in the taste of your brew. Be careful of high temps, I know it can be hard to get good temp control in Hawaii, but try to keep it under 72 F.
Cheers!
