While Wailuku might not appear to be the most exciting area to stay in, it's actually perfect if your plan is to just hire a car and do day trips- super easy to get all over the island from here. As for Wailuku Guesthouse, Maureen is absolutely lovely and was incredibly helpful when we had issues hiring a car, then had a flat tire, she even made us cookies! Room was perfectly clean, everything you need, and if you want to just chill out, there's a pool and outdoor area as well. Thank you!
