If you're a sea lover, oslo prince can satisfy most of your desire. I've stayed there for 3 nights. My room has a balcony, with full sea view facing Pacific Ocean. Room size and decoration are ok although it's a bit too basic when compare with any other resort hotel in East Asia countries.
Location is a real concern if you did not plan to join tour or self driving. Hotel is far from train station. You must make sure if shuttle bus is available at hotel. Meal is also a problem. Only 2 to 3 restaurants inside the hotel, serving meal in japanese and chinese style. If you didn't like both, sorry, you have no other choice within walking distance.
Swimming pools and water park are the other attractions in oiso prince. It's Long neck swimming pool is unbelievable long (in fact the pool is not for swimming but for people free floating with giant lifesaver.) It's water park is huge. It allows hundreds of people playing and swimming at the same time.
Good:
- good sea view
- resort style, quiet and relax
- not expensive
Bad:
- far from public transportation
- except hotel restaurants, no other place to eat within walking distance
