With its shiny black surfaces and gray-on-gray color scheme, this sleek little hotel set back on a busy Waikiki corner would be at home in any major city. Only here, the front desk clerk cheerfully hands out beach towels and boogie boards. Despite the $25 per day mandatory “amenity fee,” Hotel Renew, with its location one block from the beach, is still one of the better deals in town. Rooms are spiffy, the Wi-Fi is speedy, and a daily breakfast is included in the rate. Many guests are business travelers, and sure enough, the hotel is a fine choice for visitors who need a crash pad and not much more.
