I'm going with my family, my parents are in their 50s/60s, my sister is 26 and I'm 28. My mom typically likes convenience when she travels (e.g. easy access to everything). I prefer nice beaches - soft white sands and crystal blue waters. My sister likes to hike and is a bit adventurous. My Dad likes to golf (but probably won't do much of it b/c the rest of us don't).
The Kauai Hyatt is slightly more expensive - about $500 total for trip, but it seems to be getting much better reviews, but the pictures of the Hyatt don't look as nice or upscale.
Will the weather be better in one or the other at the end of March? (Southern Kauai vs. Northern Maui).
Finally, once I decide where to go - should I stay there 5 or 6 nights.
