Are you planning wedding week "excursions" for your guests? I was thinking it would be nice to drive up to Mauna Kea for sunset as a group and do stargazing at the visitor center after, but I know you cant really make it up there without a 4wheel drive, and not everyone will be renting a JEEP. Maybe we will do this in the days after the wedding.
We also really enjoyed snorkeling with the Manta Rays. But this is at night, and Im wondering if people will freak out, and not want to do this. Shoud we do something more friendly to everyone? I kinda wanted to do something as a group that you could only do on The Big Island.
