Trying to decide the following:

1. IC Park Lane executive room (access to club) GBP375.

Vs.

2. Athenaeum - run of house room. Price GBP250.
I know these aren't really comparable rooms, but is it worth the £125 difference?
Which would you choose? I've heard a lot of nice things about Athenaeum but just about equal positives about IC, so does it all come down to price ?

Feedback appreciated.
