Gary,
When I go to the Big Island I stay on the Wiakoloa Beach Resort area. It consists of a bunch of resorts including huge Hilton and Marriot resorts along with a lot of smaller ones. I have stayed at the Aston Colony condos which was a great deal. They are 1, 2 and 3 bedroom completely furnished condos with living rooms, Kitchens with dishes, pots, pans, refirgerator, oven, cooktop, and dishwasher, dinning areas, patios, balconies, multiple baths, and even a full sized washer and dryer....Just like home. They have daily Maid service to change sheets and towels and do the usual cleaning.
The first time I went to the Big Island, I stayed at the Wiakoloa Beach Hilton Resort (about 5 Hotels on the compound) and I had to buy food in restaurants, etc. The next time I went I rented a 2 bedroom, 2 bath Condo at the Aston Colony at Wiakoloa Beach and it was cheaper than the Hilton Resort. I went to WalMart and bought eggs, bacon, coffee, yogert, fruit, bread and fixings for sandwiches, etc. We made and ate our own breakfast, and could have lunch and snacks without having to go out to a restaurant.
The Aston Colony Villiage has a very nice pool and tennis courts and rarely is there anybody in the pool. A golf course runs right through the middle of the resort. They also have free WiFi, and I brought my netbook so I was able to check my email, and book tours and events going on around the island. I even booked airline tickets and a rental car for a day of Island Hopping to Oahu to visit Pearl Harbor, Waikiki Beach, The North Shore and the Polynesian Cultural Center, etc. That only cost me about $250 for two people, while a similar tour cost about $269 per person.
Wiakoloa Beach is about 25 miles north of Kona, and about 15 miles north of the Airport. There are some resorts in and around Kona, but they are much older and nowhere near as nice, but they charge almost as much.... The Aston Colony Condo's were much newer, cleaner, and nicer and where cheaper than nearly all the resort hotels. There are other Condo's in the Waikoloa Beach area, so if the Aston Colony does not meet your needs, you have others to choose from.
There are a few resorts a little further north of Wiakoloa Beach around the Hapuna Beach area, but they are more expensive, and I don't think they have Condo's.
If you need more info, just let me know. I can even send you some photos of the Condo I rented for a week and you will see that it is clean, modern, well decorated. If you want to see some photos, just let me know and I will send some to your email address.
