I want to disagree but you're likely right. I want to disagree because of TapuTapu making things easier. But Interesting to see if one may be able to experience volcano bay all in one day. I agree with you as well because of the park hours and the amount of amenities catering to the guests .Pretty sure you will not be able to experience all this park has to offer in a single visit. Lots of details being hidden in this.
