Spouse and I are taking the 5 and 7 year old daughters to Hawaii for a week at the Ko Olina vacation club. We will have a car. We are not owners but are going on a special offer where we have to participate in the timeshare presentation. Anyone have any tips or pointers on getting the most from our stay? How long is the timeshare presentation, and what is the format? Do the kids join us for that? Any help would be appreciated. We have never been to Hawaii before. I've stayed at HVCI units before but have not done the timeshare presentation. Apparently there is a nearby Costco where we should buy groceries/supplies for our villa? Or are there better places for that? Thanks!
