I've had a few stays here, sadly not in the last couple of years though. But every stay has been fantastic, helpful staff, beautiful surroundings and overall a really relaxing experience.
Foodwise, I haven't eaten in the Arlington, but have had several meals in Sol Oriens which have all been really good. Greens in the golf club is also very good. The food the hotel bar serves is good, but the meals are less substantial, however sandwiches were a good portion size. Had Sunday lunch in the Pub once and it was a good hearty helping but nothing I'd write home about.
Spa is fantastic, I've tried a few others but this is my favourite. The 3 hour Heritage Spa Experience is so relaxing - just remember to drink plenty of water or juice or you'll come out ready for bed!
Pool is a plain old rectangle but enough to keep the kids happy, there's also a jacuzzi, sauna & steam room.
Golf course is manicured as is the par 3. There's a nice walking/jogging track that goes all around it.
If you go, maybe you'd post back here what you thought, I'd be interested to know if it's still as wonderful!
