If anybody can help me find a better rate for 2 rooms for 4 adults on 28th and 29th Aug in a fairly central London hotel (not airport) I would appreciate it.

Rates on Marriott.com (per room/night) are:

Grosvenor Square £170
Park Lane £217
Marble Arch £150
Regents Park £116
Chancery Count £169
County Hall £206
Maida Vale £105
Kensington £119
West India Quay £79.20
Apts West India Quay £139

Both rooms will have gold card members if this is of any help or advantage.

Thanks in advance for any help.
