Wanted £250 upfront to put a timeshare property on their website... But refused to send out ant form of communication in regards to acknowledgement of agreement, terms and conditions etc. Not even an e-mail, never mind an actual real contract of some sort...
The standard should "apparently" be that you pay no money up front and any monies due (commission, etc...) is taken out of the sale value. But just as regulation tries to cut down on one form of pre-payment scam, they just rename the fee to something else... and it carries on...

So, to summarise:
1. Do not pay ANY monies up front, no matter how inflated the figure you can apparently get for your week/points/etc.
2. They will become very pushy and aggressive when you do not want to pay money without first receiving some form of contact/documentation.
3. The timeshare re-sale market is a mess (and that was before the current economic nightmare). Never mind trying to sell, just try and get out of your yearly levy and you will be doing well...
4. Do your research. They rely on people not reading what can and cannot be done.

And the final point... prepare yourself...
If you think buying/selling a house from an agent is painful and dodgy, dealing with the people in the timeshare industry reaches whole new levels of pain. It is riddled with dodgy practices and scamy people...
(... and so much for (self-) regulation...!?)

Finally... Name and shame...
Shellly - Sales?
Very pleasant until you ask to many questions...
Penny - Reception
Obviously used to dealing with irate people... Suggestion, get out while you can... they will change your whole perception of what is normal.

Vision of the world UK company blackmail me with upfront fees worth of US$ 450.00 to sell my time share and after that never heard from them.
