This topic has been long but I'd like to share what I have been through.
I have completed my holidays with my wife few days ago at Wyndham Sea Pearl Phuket for 5 days 4 nights through Bleeps Vacation. The offer was 2 bedroom for 4 or 1 bedroom for 2 (Bali or Phuket) but I took 1 bedroom for 2 with jacuzzi in Phuket. Package includes breakfast and 2 way airport transfer (Benz)  .
True enough that you need to pay "Refundable No Show Deposit" and also flight ticket before confirmation. Deposit may be around $350 depending on number of nights and location. You also need to attend a presentation by Wyndham Asia Club for about 90 minutes and of course the idea is to sell you the membership but no force are being made. If you can afford, go ahead or else you can turn them down.
It is not a scam. Put some money a little bit, then get back later and enjoy the holidays. However, I think the membership is worth buying for those who like to travel as they have Wyndham worldwide but it's not cheap
