mmm that's cutting it really fine as it normally takes about a week to receive it back as in the case of my wife.

The positive side is your application is on a Monday and you travel on the following Saturday, so they are all weekdays to sanction it but the only advice I can give you is to stipulate your situation to TLSCONTACT and maybe just maybe they can notify the embassy of the urgency in your case, its worth a try...Good Luck...
