We just got back from a gorgeous week at the Royal Pacific.
There are activities at the pool area every hour between 12pm and 6pm every day of the week weather permitting. Musical Hula, Bean Bag Toss, Big Splash Contest, Water Balloon Toss, Trivia, Sandcastle Creation, Land Sharks & Minnows, Ladder ball, Relays, Buried Treasure, and Noddle Ball were the activities listed. My 13yo nephew went to pool by himself a few times and said he won free smoothies.
Movies are shown by the pool on Tuesday, Friday and Saturday.The dive-in movie we watched was Robots. Sorry didn't get the list of other movies but if u call the hotel directly they can probably tell you. They even provide fresh popcorn.
DH and I stopped for the italian ice on the way to the water taxi. We had to ask the server at the bar since we didn't see anything. She went in search of it for us so we tipped her for going out of her way.
In summer when we are there its usually 1pm till 7pm, every 30 mins usually they have something going on like PP said, and there is always people in playing volley ball, so something always happening, and they are free.
