I do think she thought they could get in to legoland, but I don't think any part of the holiday was gifted.
I fully get the urge to go and do something spontaneous, I've been tempted a few times to just go ahead and drive to the seaside for the weekend, or book a Haven holiday but I don't, because common sense kicks in. It is hard work looking after two kids alone, so I don't get why she's made it harder for herself by going on a mini break when she could have so easily have done the same thing in England. Those kids are going to be exhausted this week.
One of my 4 year old's favourite things to do is go on a 'park crawl'. Three or four parks in a day and lunch at a cafe. He wouldn't enjoy a weekend to Denmark any more than that.
