Barely a Family hotel.
Not advised for early rising families. Children below 3 are not allowed to use the indoor playroom until family time at mid day, even if the parent is in close proximity. Our child is 2.5 years, potty trained and attends school. His only option was to go into a small room for infants at a surcharge or wet his clothes outside as nothing was wiped down. The outdoor chairs at the play area were not wiped down from overnight rain. The trampoline was wet, no night covers so kids get wet waiting for the play room to open at 9:30am. Swings and slide not wiped down either. The indoor pool only opens at 10am. Football balls were soft which shows a geberal lack of care and attention. The kids play centre closes at 16:30. I shake my head in amazement. What on earth are parents to do from 16:30? Descend all at once to the indoor pool? Imagine a hotel full of buggies and 50% of them will pass stairs to their room without a ramp. It’s disgraceful. In the evening you can order the bar menu but the tables are not setup to eat as the tables are knee height. The main restaurant only serves a buffet of very very average food or you can order room service. The purpose to visit this hotel is to have the kids taken off your hands for a short while and regrettably this is not what the hotel delivers. Mid day to 16:30 access is all that’s provided and it’s self service.

If you have kids under the age of about 8, this place is perfect. If, however, you have teenage kids, there is very little in the way of activities for them to do. The tennis academy wasn’t running when we were there (not enough interest), and there weren’t sufficient numbers to run other activities.
