Unfortunately, inexpensive accommodations are few and far between on Oahu, and especially in Waikiki . . . . at least places that you’d actually want to stay in. But a good bet is the Aqua chain. Its inexpensive to moderately priced properties (from $119 a night) are managed by a Hawaii-based company. Hotels do range in quality (with furnishings from dated tropical to bright and modern), but they are generally clean, well-maintained, and regularly updated. Another plus? Free Wi-Fi! And we’d say this is the stand-out of the chain, as it’s located right in the middle of Waikiki, about a 10-minute walk from the beach. It has spacious rooms (including a 450-square-foot one that I found for just $125/night online), many with kitchenettes, and is quite well maintained.
