Royal was super easy to work with. The studio was clean and well stocked with just about everything you need. It is within easy walking distance of Princeville Shopping Center. Make sure you check out the shopping and dining here. Royal keeps a good selection of reference books on Kauai in the studio, so you can plan your excursions.
Wyllie's beach is a short walk from the condo, but the trail can be very slick on the steep portions if it has rained recently. Make sure you take advantage of all the North Shore has to offer.
If you are a light sleeper, make sure you close the windows at night. We were first timers to the island and didn't realize that chickens are everywhere. The roosters start crowing early, but we found happens everywhere on the island.
