So the wedding people at Cosmo got back to me about hiring Suite #3678 which is the "Reception Suite".
They quoted me $350 per hour rental and a minimum spend of $80 per head... way too much for me, and they totally missed my point about only wanting it for "after-dinner" drinks after spending a few thousand dollars on dinner at The Wicked Spoon (in THEIR hotel!).
Anyway, Ive attached the files... if you are interested.
Ill just be calling them and booking the Wrap around terrace, and bringing my own drinks!
Ok - so looks like I cant attach the files. If you want them, please email me at samara_matthews (at) Hotmail dot com.
