The "Best Price Guarantee" applies to the rate for room nights only. Promotional packages, deals, or bundles that may include additional amenities such as parking, meals, entertainment, etc. are not eligible. So the cheapest rate (for the Spa, Food, Play)wasn't eligible for a refund, but I did get $11.49 (which included some taxes) back after an easy five minute phone call to 1800 PRICELINE. The rate difference was only $1.05 from what I paid, but she said it would have been 53 something with tax. I didn't argue. Thanks for the tip. Love the site!
