We stayed at the aparthotel Bonaire about 18 months ago with another family. We all had a great time no complaints about the hotel or the staff who were very friendly.
Our daughter even got a birthday cake and a bottle of fizz for us. We did'nt tell them it was her birthday so dont know how they found out, but, it was a very nice gesture and one they didnt need to make.
The buffet is very good, we did'nt take the halfboard option as buffet are normally pretty awful. But we ended up using it most nights, especially good for children, a lot of variety.
The kids loved the evening entertainment, dancing to Star Trekking etc a groan for the parents but its great to see the kids having a good time,they also loved Thomson the Dog.
We had a great time, a lot of good facilities at the hotel to keep kids amused. Beach was nice kids loved cycling up and down the promenade. Cala Bona is a very nice resort, there are some good restaurants and it has retained some charm.
Hope your holiday is as enjoyable as ours was. If I think of anything relevant I will let you know.
