Parkdean Resorts complaint: Unfair treatment

My family of 6 arrived on Saturday 17 July in Tummel Valley Parkdean. At the reception area there were notices stating the restaurant was closed for the week due to covid. I spoke to a staff member who also advised that all children and adult entertainment was cancelled for the week and they have very few staff on site.
My children were disappointed that the entertainment that was promised was not happening. I stupidly thought some form of compensation would be offered.
2 days later on the Monday afternoon (after new holiday makers have arrived or on their way) a letter was delivered to all caravans stating due to covid all entertainment was cancelled and restaurant closed. Conveniently they wait until people arrive and can’t cancel before providing information that was available several days prior.

My children spent some time over the week in the arcade, only to find at the end of our break that no staff were available to man the arcade shop for them to spend their winning tokens, so they lost their money and staff just said sorry but they can’t help.
I paid extra before the holiday for a fairy trail walk for my daughter, but when we arrived for it I was told I assumed you’d figure it was cancelled. They said they think I will automatically get refunded for the excursion.
We then decided to leave a day early due to our treatment and I then started to contact them via messenger chat to ask about compensation since we did not receive what I paid for. Families book parkdean for the kids entertainment, which is included in the cost.
I was told as per terms and conditions they are not liable for any compensation.
I am disgusted that they take full price and when they can’t deliver what has been paid for, they’re not interested.
