user: What's the appeal of a vacation rental on the Big Island of Hawaii?

assistant: The Big Island of Hawaii is a bit quieter than the island of Oahu, where Waikiki Beach is. While Waikiki is a beautiful beach and place, the Big Island of Hawaii has so much to offer that is unique only to this island. First, you can visit black sand beaches. This is due to all of the volcanic activity on the island. There are still active volcanoes on the island. You can also take tours around them should you wish to get closer. You still get all the beautiful beaches Hawaii offers, but with features, you can't find on the other islands. Also, if you want a slightly less touristy destination, the Big Island is for you!
