As it gets closer to our visit (we fly in on Wednesday afternoon) it looks like we will be in for rain several days of our visit (12/17-12/25). Since we were planning on doing alot of exploring & beach days (mucho snorkeling), are we in for a change of plans? Or are the rains short lived & non-eventful? We are staying in Kailua-Kona but planned visits all over the island. Don't get me wrong... I know that being there will be better than here! :) Just wondering how much the rain can impact our plans.
