I am booking a trip to Hawaii for my entire family, which will include airfare for 12 from CA to HI, then three condos, one for each family. I would like to insure this trip, in case we need to cancel it. I need to be covered, so if just 1 of our party becomes ill and cannot go, that we are able to cancel everything. Since I am booking all of this myself, I would very much appreciate any referrals you folks might have on booking this insurance. Thanks!

Depends on your needs! You might look at insuremytrip.com or squaremouth.com, each of which allows you to compare plans on the basis of specific features and costs. Just be sure to purchase your coverage as soon as you can after actually putting any money toward the trip (e.g., by purchasing air tickets).

Also (VERY IMPORTANT), make sure you read and understand the terms of the policy you purchase to be sure it covers the type of loss you wish to insure against.
