It is certainly possible to receive guests in your accommodation during your stay. You must notify the park reception if the guests stay overnight in the accommodation. You will be charged for the cost of the bed linen and council taxes for the guests. It is only possible for guests to stay overnight if this does not exceed the maximum number of people that are permitted in the accommodation.
Please note: if visitors stay overnight, the number of beds in the accommodation may not be exceeded. In other words, in 4-person accommodation, a maximum of 4 people may stay overnight.
