I think ultimately it’s case by case. You have to weigh up how long you will be in the park for and how much there is to do, and the general quality of the product on offer.
UK Merlin parks are all overpriced but as we all know that’s just a byproduct of their model of flooding the market with vouchers. For me the Merlin parks are £30-£35 parks, if you wanted me to give an honest bracket of what I think they’re worth. None of them though represent the level of quality and service I’d expect from a true £40-£50 priced park. Yes, vouchers and deals make it feel like you’ve got a good deal, but the expectation is still set high by the initial price.
Pleasure Beach has always felt like a bit of a steal, but on the flip side, it probably makes sense given a trip to the park would be a part of a bigger Blackpool holiday for a lot of guests, so disposable income may be getting eaten up by accommodation or similar.
You have parks like Europa, Phantasialand and Efteling who never really seem to have much in the way of offers. They aren’t cheap, sitting in the £40-£50 bracket, but offer a full day out (or multiple days) and I always feel offer good value for money with the sheer amount of things to see and do. I’ve never come away from any of the parks feeling like I ran out of things to do, which is how I would measure a park’s price:value ratio at that level. I will admit I think Phantasialand push it a bit though for even a premium offering, sitting close to £50 and more expensive than Europa. Fine if they’re doing the return ticket offer, but that’s not always running.
For me though, if I can pick up a ticket to a park at around the £25 mark I’m generally not too concerned about what I get. There’s parks like Walygator for example which sit in this bracket. I’ve paid that, gone in, rode Monster a couple of times, hopped on the Vekoma and rapids, then left. I didn’t feel robbed and came away satisfied. Again though, I appreciate that’s quite different to some people with different levels of disposable income.
Then of course you have the Disney’s and Universal’s which offer a great experience but are more akin to the “designer” brand of park. Again though, DLP is a perfect example of a park where you can rarely pay full price, especially if booking as a holiday. We’ve had 4 days, stopping in Newport Bay with full board for something silly like £350 each before!
