We loved our stay at Jacklynn's property. The location is relatively remote, but you're only about 30 minutes from Hilo and 50 minutes to Hawaii Volcanoes National Park. Our group consisted of 18 friends and family. We generally cooked in each night, and we found the kitchen to be well equipped for cooking for a crowd. The house and cottages were perfect for our group and gave everyone a nice mix of togetherness and separateness.
The internet is satellite-based, so it's not the world's fastest or most reliable connection. If you're trying to do video conferences, it might be tricky, but it worked well enough for most other activities.
