We had a great 5 night stay as a young family of 5 (kids aged 6, 3 and 1) here and had a fantastic time staying at the Lalandia lodge. It was clean and had everything stated, we were provided with a cot and checked in at the reception, which was easy to do. One thing to note is that you get charged for bedding and have to make your beds yourself. Also you get charged for energy and water costs but when we went in October, although it was cold, the lodge was very warm and we didn't have to turn the heating on during our stay.
The activities provided were great and we made use of the swimming and softplay that were included with staying at the lodge. Our 6 year old could access most of the activities, which we did a pay as you go. He did: ice skating, tobogganing, wall climbing, mini golf and zip wire and as a family we did bowling, shuffleboard and football pool. Pay as you go worked well for us as our 2 younger ones couldn't access everything but if all 3 of them were over 6 years old, we would have booked through the Lalandia website and booked the gold wristbands where you can go on all the activities unlimited times during your stay but you have to buy them 5 days in advance and the whole household have to buy them.
We tried all the restaurants and they were pretty decent. It did get expensive though so we made use of the supermarket there and had a few sandwich lunches. As a kitchen is provided at the lodge, we saw many families buying groceries to cook dinner too.
