The two-bedroom hotel room is actually quite roomy especially if you're coming from a hotel in Japan where you barely have any space to move around. The beds are large enough to hold 2 people each so that's a lot of space to roll around in if you're not a sound sleeper.
The complimentary breakfasts are on a per day basis depending on how many of you checked in so if you say 2 people for 4 days then you get 8 vouchers which is pretty generous by modern standards, and the breakfasts have enough variety
The shuttles that go back and forth through the hotels, outlet mall, theme park, and kaohsiung city are either free or significantly cheaper than if you take a taxi, and going to the city takes like 40 minutes tops so if you wanna look around then there's no problem.
The nearby outlet mall is filled with off-price retailers that permanently sell on massive discounts from innumerable fashion brands and to a lesser extent tech brands all over the world. A lot will say around 80-90% off, and this is a tactic to let you know that the factory outlet is selling it's overruns or last season's designs at cutthroat prices which is very very true. A 24600 ntd coach bag may turn into a 9600 ntd one for example.
Though its not a disney land the theme park is extremely kid friendly while housing big thrill rides for those teens or you adults out there, and it doesn't involve super long lines and walking till you're sore.
