I stayed in the ATH this year and quite enjoyed it.
The food at breakfast was decent, and all the staff were lovely. Our room (Moon Voyager) was clean, although it looked a little worn. Check-in and check-out were quick and easy. I quite like receiving an email or text when your room is ready.
My gripes were:
1) Touch screens for checking in. Two staff members were going through it with guests when we checked in. Why not have a desk there, and these two staff members check you in anyway? Radical idea, I know!
2) General upkeep of the hotels. Everywhere appeared clean, but both hotels (more so ATH) are very worn and outdated. You feel robbed of the inflated prices when a Premier Inn or even Travelodge can offer you a more modern room or hotel with a better bed!
3) ATH lake/garden area. What a disgrace this is. Overgrown with weeds, everything looks like it's rotting away. At Scarefest, there is no theming around the lake area. This whole area is probably the worst part of ATH. It's shameful, given how beautiful of an area it could/used to be.
4) Food availability at breakfast. We enjoyed the food at breakfast. The issue was getting the hot food! Only one station was in use, and limited quantities were being dished out when the restaurant was full. The minute some food (fried eggs) came out, you had to be quick if you wanted it. I'm still disappointed that only basic coffee is available for breakfast. Then, they have the cheek to advertise the Coffee Portal on each table. ‘Want a latte for breakfast? Tough, pay for it’.
5) Bars/no entertainment beyond 10/11pm is poor. We arrived from the park around 9:30-10pm at Scarefest. Entertainment stops at 10. Bars close by 11 or earlier. The arcade closes around 10. No times are advertised for closures (only openings), so you wait excitedly to be told when to bugger off and go to your room like a naughty child. I appreciate that it's a family resort, but the place could really do with a small adult-only bar open until 1am, with some jazz music or something similar playing in the background.
I do feel the overall product has degraded. The product experience needs improving compared to how it used to be in the 1990s/early 2000s when staying at the resort felt very special. In the bigger picture, ATH particularly needs a complete refurb. It feels similar to the park, where it needs a lot of investment. Otherwise, the resort and theme park will continue crumbling until the whole place is shut down.
