I tend to agree that most of the hotels on Bath road are more or less the same.
I would decide on price if that is relevant to you.
Personally, I like the Sheraton Skyline as I can take the complementry AVIS shuttle and then just walk over to the hotel from the Avis station. It is much quicker than waiting (and paying) for the Hotel Hoppa bus. The walk from Avis to the Skyline is about 5 mins (3mins if you cut throught the carpark behind Avis..). This option is however only valid if it's not raining...
