Sandy Shores Lodge is on the park in Towyn. It's a modern lodge, detached, so you've got your own space. The beach is a minute's walk away. Literally, you cross the road and you're there.
It sleeps six but it's got two bedrooms. Both have their own bathrooms, which is handy. It's got a 4 Star rating. It's comfortable and new, not old-fashioned.
The living area is all open plan. Kitchen, dining, sitting room, all in one space. There are grab rails in the bathrooms so it's suitable if someone's a bit less mobile.
Outside, it's got a patio with a table. You can sit out there if it's nice.
The park itself has things like crazy golf and a high ropes course. You can use all that. There's a pub nearby and a golf course.
You're right on the coast for walking. Conwy is about a twenty minute drive. It's a proper castle town. Llandudno is about the same, the other way. If you want mountains, Snowdonia is half an hour's drive. The Snowdonia National Park site has walking routes.
Inside, you've got a TV, WiFi, and all the bedding and towels are included. There's parking right outside the lodge. No pets, sorry.
