My family and friends recently stayed at Royal Decameron from December 30th - January 1st, 2023. We definitely enjoyed our stay.
The plus - The property grounds were beautiful, the beach was glorious, and the overall service was good. Food selection and taste were adequate, but nothing to write home about. I loved the evening shows for kids, a little short, but good. The dance performance by the Royal Decameron dancers was great, it was very entertaining. The number of pools and lagoons I found appropriate for the resort. Plenty of lounge chairs, if you cared to reserve early by placing an article of clothing or towel on it.
The minus - lack of organization regarding water sport equipment rental. Tough reservations were made one we still experience 25 to 30 minutes wait times due to oversold appointment slots or equipment maintenance. The furniture in the rooms is serviceable, but clearly outdated. Additional bed lines (blankets) cost extra, which I've never heard about. Lastly, we did not like that premium alcohol was limited to does with certain packages, without the opportunity for another guess with a lesser package to pay for it. I only drink certain kinds of top-shelf liquor and I hated being limited to unknown brands.
Overall, I will still recommend this facility, but know that this is not a 4 star resort, but still a safe and fun place for families and couples to vacation.
