I was thinking Couples used to offer an early bird guarantee... where if you booked early and then a better deal or promotion came along, they would allow you to take advantage of the better deal.

I had booked a trip to CSS thinking it was a great deal (7th night free promotion)... and then two months later they come out with a 7th night free AND $300 resort credit offer. Our trip (May 2013) was within the date range they advertised but our attempt to add on the resort credit was denied.

We would like to book our 5 year anniversary trip for the following year (2014), but now relunctant to book early and lose out on a better promotion.
