Great stay. Kids loved the water park. Breakfast was a bit meh and no coffee. Staff was super friendly and helpful. Facilities/room were clean. We'll be back!
The staff was very friendly and even if not directly helping were if we had questions or even just offering towels or extras. Lifeguards were very understanding of my special needs child and willing to engage everyone even if it was busy

Room was clean with a nice view and breakfast was excellent!
Thank you!
Room was very clean, staff very friendly, waterpark was fun and not run down as ive seen in other reviews. Food and stay was very reasonably priced and a good variety of choices at the continental breakfast.
The hotel is a little outdated but still clean and comfortable. Every staff member we encountered was amazing! Friendly, helpful and very accommodating. The arcade needs some work with half the games out but the pool and all its features were awesome and they had a cool kids zone full of activities. Overall it was a great stay and we would definitely go again!

Loved our visit, pool floor has been resurfaced and feels nicer. Lifeguards are well staffed and actually use their wissles. Breakfast seating is always an issue but delicious, we ate in our room. Some stains/ wall wiping could be done but overall bug and debris free room. We will be back some day, keep up the good work!
This was a middle point to meet family members. We had all ages and the pool was wonderful for all ages. The rooms were clean and comfortable. This will become a family meeting point for us in the future. Kids loved it.
