I want to add or remove a travel companion. How do I do that?

You can easily do that yourself in your account. Go to the details of your booking. There, under 'travel company', you will find the details of your travel companions. Here you can add or remove a travel companion. These can be travel companions who are staying the same number of days as you. But also guests, i.e. family/friends who stay for one night, for example. 
 
Based on this, we will recalculate the total price of your stay, which includes an increase in tourist tax. We will inform you of this adjusted amount by e-mail. Have you added a travel companion? Then you can pay the additional amount under 'payment information'. We will then make sure that extra beds are made and there is also a set of towels for the guests. 

Will someone no longer be coming and you have already paid for this? Then you will receive this part back from us on arrival at the resort.
