We're (a retired couple) heading there in a few weeks. I'll plan to report back. In the meantime the reviews on TripAdvisor have been quite compelling. You might be able to glean something about family visits there. You can also e-mail the hotel at

FWIW, the location is quite far south--pretty close to Panama. San Jose airport is probably the better choice to use. You will need to fly from SJO using Sansa (single engine Cessna planes) or plan to drive about 6 hours. My research about flying into Liberia did not favor that option.
