When we vacation, we eat most meals in the villa...unless we are out and about site-seeing or out to a nice dinner. Plenty of restaurants near Maui Ocean Club, in case we opt to not cook at all.
We enjoy the full kitchen that most MVC properties have within the villa. But, we also get by fine (as a family of 4) at properties like Maui where the old villas have no cooktop/oven. We are not professional chefs by any means. We just select our meals to fit around use without a cooktop/oven. Breakfast is cereals, muffins, fruit, juice, coffee, milk and even pre-cooked bacon which can go in the microwave. While not optimal, you can do eggs in the microwave with the right additional tool. Lunch we do sandwiches, salads, veggies, deli meats, chips, etc. Dinner is the only slightly harder meal...as you cannot cook pasta dishes or meats. You can buy microwave pasta meals, which sometimes is okay. We tend to try to grill a lot, which we enjoy on vacation (as long as the weather is good).
For Maui old villas, the larger fridge was a really nice addition and step forward. It makes a big difference in storing cold food, milk, juices, left overs, meats, etc. I do wish they would install convection microwaves, which is a small additional cost difference...but would close a basic gap on the oven portion. Then just use the common kitchen for cooktop needs.
