Thanks for the replies.....
I spoke with PW also this morning. They told me much the same thing. They need 24hours notice to turn it on. The problem I had was that the AirCon people were coming today to make installation. PW made every effort to get things turned on for their arrival, but finally there was some "fuse" problem that couldn't be resolved until this afternoon - so the installation is delayed until Friday. The AirCon company had their own generator with them, but the security on the site would not allow them to use it????
A few days delay is no problem... I don't arrive there until 9th August anyway.. On countdown now.... Seems to be taking FOREVER though....
