Visited this hotel a while back and it was everything I wanted.
My friend and I got a late deal and had such a relaxing time.
The staff were brilliant including the entertainment guys who work really hard, drinks were great and the bar staff are great.
Loved the fact a there are 3 pools so you had a choice of where to go.
The room was brilliant with a good sized bedroom, bathroom and cooking and lounge area. We were all inclusive so didn't use the kitchen but was nice to have a fridge that you did not have to pay to use.
Only downside was the 24 hour reception was difficult to get into at 4am and we had to go back to our room to ring them to let us in to check out.
Overall a great time.

nice hotel and outside entertainment was brill as you can keep nice and cool the entertainment team work very hard all day and evening, no loud music after 11pm so you get a good night sleep, pools are clean and warm, food was nice breakfast just warm but ok never got ill from the food, evening meal was nice and hot, and piza at snack time was nice as we never had dinner as we were always full, free ice cream all day was the best way to cool down by the pool and a nice walk to the town in the evening to walk your meal down with no hassel was nice. i would go back again

This hotel is 10/15 min walk to the centre if you know how to walk!
Dont go right from the reception but walk down passing the beach om you left hand. Within minutes you will see the major street to the centre with a lot if shops, restaurants, bars and supermarkets. At the end of the street is downtown cala dor.
Rooms in block 9 have pool and seaview. Be aware that you dont get à room above the entertainment stage!
Food was excellent. We had half board, à bottle of wine cost only 3,5 euro and it was Good too!

Stayed at Ferrera Blanca in May half term with my partner, our 2 young children and grandma!
Can't fault the apartments. Nicely renovated, modern with large balconies. The complex is spread over 2 sites, separated by a road. We were in block 16 which is the furthest away from everything but nice and quiet. We would have preferred nearer the beach in block 8 as this is also near the restaurant, the best pools and the best view. Avoid block 12 or 14 if you don't want a view of the entertainment stage.
The staff were very pleasant. The ladies who cleaned the rooms were super efficient.
This was our first time all inclusive and the food was good in the main restaurant. Plenty to choose from. Pizzas in the italian are just about edible - smothered in too many dried herbs! The wine is pretty good and there is plenty of choice of drinks.
The hotel has 3 separate swimming AREAS with 5 pools. The area near the restaurant has 2 pools and is very nice but was not suitable for my children (aged 5 and 7) as the depth was between 1.2m to 1.5m (no shallow end). Probably best for adults who want peace and quiet. Then there is another separate area with a baby dip pool. Too shallow for my children. Unfortunately the pool which was suitable for my children was in the main entertainment area and this was our least favourite area because they played loud music all day, there was a bed and umbrella shortage and all the bins were infested with wasps!
My main problem with this hotel was the lack of umbrellas. There were only a handful of fixed ones which were taken very early in the morning. We considered buying our own umbrella but there were no bases to stick them in anyway. This would be a real problem for babies or people who like a bit of shade (like grandma!)
The kids disco is fine for under 4's and starts at 8.30pm but it was too babyish for my 5 and 7 year old. I enjoyed the bingo at 9pm but the entertainment which starts at 10pm is very poor...but hey it passes the time away!
The beach is right on your doorstep and in my opinion is one of the best in the area, as is Cala Marcal beach. Umbrellas/beds are 12 euros a day. The cafe on the beach is lovely and serves fab ice-cream and coffees.
I was very dissappointed with Cala D'or itself. A sprawling mass of souvenir shops, children's rides and poor restaurants. It really depends on what you like but I much prefer the resort of Puerto Pollensa.
Overall, I was disappointed with this holiday. I would rate this hotel as 3 star, not 4. I have come to the conclusion that I much prefer our usual small, self catering apartments in picturesque resorts, rather than huge, all inclusive complexes in overdeveloped resorts - but I suppose we live and learn!
