The question was is if it's worth it to move to VIP gold so we can only assume he purchased retail and is VIP.
Purchasing 200K points to go gold retail can be very expensive but there are cheaper ways to do it and still be VIP gold. Resale won't count but you can look for resale Wyndhams from them typically deals like $14,000 for 140K points plus 140K bonus points. Still expensive.
There is another new option loan assumption which can be cheaper. Typically something like 175K every other year points for about $7500. With this option you pay any arrears lets say $1,250 and take over the remaining payments balance of $6,750. Still no where as cheap as ebay but cheaper than full retail.
Now what does it mean to be VIP gold vs regular VIP?
* longer window for discount on points, larger discount 35% versus 25%
* Longer window for free upgrades
* Ability to specify room
