Not every "kids club" is the same thing. Age cutoffs, staffing, and hours vary enough between these hotels that the wrong pick means no dinner alone. Here's what each one actually offers.
It doesn't have a kids club. It doesn't need one.
Mikazuki doesn't run a supervised program, no sign-in sheet, no staff-to-child ratio to check. Instead there's a full water park: multiple slides, a lazy river, a wave pool, and splash zones that keep kids 6 and up occupied without anyone organizing a craft session or watching the clock for pickup. If you're used to booking around club hours, this removes that constraint entirely, because the entertainment is self-directed and open all day.
The tradeoff is supervision. Nobody is watching your kids here except you, so it suits families who want to be poolside together rather than handing kids off for a few hours. If that's the trip you want, this is the pick.
The location is real. Mikazuki sits roughly 20 minutes from the main My Khe / An Thuong strip depending on traffic. That means less walking to beachside restaurants, less An Thuong nightlife, and more Grab rides if you want to explore central Da Nang. Book this because you want the resort to be a major part of the trip, not a base for it.
