I didn't think that Carriage Hills had fixed weeks, just floating red or white weeks. I own a week there and it floats.
So, assuming that what you have is a floating red week being offered to you take a look at eBay auction #160050535894. That was an every other year red week which sold for $539.99 US funds + $549.00 US funds closing costs and resort transfer fee. I thought this was very very cheap. The last red week I saw sold went for around $2,500 or so (every year).
I bought an every other year white week for $865 US dollars + closing costs a few years ago and thought I got a great deal.
If you have any more questions, just send me an e-mail and I'll try to help further.
