I've been to this hotel several times, and in fact it's the only Eastbourne hotel I've ever returned to. Judging by the other comments here, there are two very different experiences depending on which room you secure. I've always booked a Sovereign (premium sea view) room on DB&B, and been pleasantly surprised by the size of both the room and the bathroom. There's really nothing nicer than curling up on one of the big armchairs, snuggled into their fluffy white bathrobe, watching the early birds on the beach through the massive sash windows and waiting for the breakfast tray to arrive!
The food in the restaurant is pretty good, and v good value on the DB&B option, and I'd challenge you to find a more pleasant and professional restaurant manager anywhere.
At the end of the day, this is an honest and hardworking hotel where you pays your money and takes your choices. If you can afford to pay that little bit extra, it's well worth it.
