The Marriott is a beautiful facility. Mostly families come here and it is a good environment for kids. The facility also includes many daily activities for adults and kids that are included.
Eating at the facility or Koolina can be expensive but Kapolei is only 10min away with many options to eat. Otherwise, we found Koolina to be a bit far to most places we wanted to see or places we wanted to eat at.
The lagoon is protected and has no waves, therefore is great for little kids. If you’re looking for waves or good snorkeling, look elsewhere.
Overall, we had no issues with our room itself and the staff was courteous and helpful. It was the Koolina location itself that we were a little underwhelmed with.
