Hattie lives in a £1.8m ($2.2m) mansion with mum and dad, and as a result, is used to the finer things in life, such as skiing trips and holidays to Sri Lanka.
But taking part in a new episode of Rich Kids, Skint Holiday, the 19-year-old was taken out of her comfort zone as she went a £180 ($220) camping holiday with the Hayward family from Berkshire.
Dad Pete runs his own oven-cleaning business, while partner Louise is a weight loss consultant. But due to a lack of finances, the couple have never taken their two daughters, Kadie, seven, who has autism, and Chloe, four, on holiday.
Pete admits: "We're both self-employed so it can be tricky to get the bills covered so this means we've never been on holiday as a family."
But unfortunately for Hattie, this isn't the swanky kind of luxury she is used to - even getting the train to the camp site and carrying her own bags is an unexpected chore.
She says: "I'm not used to getting on trains to go on holiday, I normally go to the airport.
"When I usually go on holiday I don't have to do anything.
"I'm used to the staff at the hotel taking my bags and putting them in my room."
And from here, things don't get any easier, as Hattie has to set up her own tent and eat food which Pete and Louise - who have saved up for six months for the trip - brought from home to try and cut down on costs.
Eventually, sat in her tent, it all gets too much for Hattie, who is brought to tears by the stress of it all.
She says: "I thought I would be able to handle more stuff."
And while the Haywards struggle to make ends meet, Hattie - wearing her £800 ($980) Gucci trainers - admits she's not used to such hardship. If she wants something she gets it.
Shocked by the young woman's level of privilege, Louise says: "It's quite tough to know that for some people it's just that easy. We would love to be in that position and to have that disposable income.
"I wish I could spend money like that because it would make such a difference to the kids."
The next day, Hattie and the Haywards rise for a day of activities, visiting some of the animals on the campsite's farm.
After a £15 ($18) picnic for lunch, the family have spent £17.50 ($21.50) of their daily £40 ($49) budget, and Pete and Louise get Hattie to spend the remaining £22.50 ($27.70) on their afternoon activities and evening meal.
Now, never having to budget for things - she receives £500 ($616) a month from her parents for travel so she can use her wages for treats - Hattie is surprised by how difficult it is to budget.
In the end, she decides to go on a wildlife walk through the woods with the family - and it's a hit, rekindling her own love of nature.
The teenager then cooks a bizarre mix of sausages, rice, sweetcorn and baked beans - but it still goes down well with the Haywards.
After dinner, Louise admits that because of their financial constraints, the family find it difficult to plan activities tailored for Kadie's autism.
Shocked by the revelation, Hattie says: "I had knee problems when I was younger and needed some surgery, which my dad just sorted out for me.
"It's hard to realise that money can have an impact on someone's development - but it can."
But it's not just Hattie who has learnt something from the trip. Dad Pete says it has inspired him to change his life.
Over breakfast, he says: "I know there's more I could do for my family. Listening to how your parents grew up has inspired me to better myself."
To thank the Haywards for allowing her to tag along on their first family holiday, Hattie then reveals that she has organised a day with horses at a centre that specialises for people with autism. Another hit.
Looking back on her trip, Hattie says: "I need to stop spending money on stuff that I just want and I don't need.
"I would just chuck money around like it was nothing but seeing how much they struggle, it's made me understand."
Rich Kids, Skint Holiday is on 5Star at 9pm tonight.
