purrine, yeah she was our coordinator too. dunno if there's more than one... my DH was quite pissed on the day itself coz we couldnt reach her at all and she didnt pick up her phone. she only turned up when everything has been settled to ask if they were ok (of coz ok already when you turn up at the end of everything). plus, many times she wasnt clear when telling us things. but her waiters were good, so we communicated to them and the captain our requests, and they settled it for us. dunno why we even needed her if thats the case.
the first few courses took quite long too, so we had to chase them, but subsequently not such a long wait between dishes. oh, make sure you get a friend to monitor the wine too. we ended up with 2 half bottles of red wine and 1 half bottle of white.. make sure they finish 1 bottle before they open a new one.
also, try not to rely too much on her lah on that day..
25 tables now sound like quite a tight squeeze.. will you use the private rooms? but if you use private rooms, your guests will feel so isolated! maybe you can see if they have a wedding for 25+ tables and go down just before the dinner to take a look and see hows the space like.
