Our experience here was better than average based on the reviews. For travel on a budget, we had a great time. There were plenty of things that didn't work, or weren't available, but I found myself enjoying the things that did and were.
We had some standout staff members who were super friendly, like Faustino and Fernando, that made us some of the best margaritas we have ever drank! The food we had was flavourful, served quickly, and felt good to eat (no sickness here). The room was comfortable, clean, and quiet, even during the storm that came in through the week.
The downsides were mostly that some of the facilities need maintenance. Our AC didn't work, and neither did the jets in our jacuzzi (though it did get clean hot water!). Apart from that there were some limited options when it came to food, even running out of beer entirely for a day.
A few more staff, more frequent restocking, and some maintenance would have made this trip a 5/5.
For the price we paid, with the expectations we had, I would recommend Kore to anyone traveling for all-inclusive on a budget.
