Thank you again for all your helpful posts.
Nonetheless, I must say that the Marriott Queens Park is definitely not in the same league. Rather there are worlds between it and the banyan or the InterContinental. It's a huge, old building structure, tiny bathrooms, zoo-like lounge that is full of obnoxious people.

For people looking for a more luxurious experience or an intimate club lounge, better stay away.
