OK, so I found a room for EUR 96 (room + breakfast) on Expedia.com (including all taxes, fees, etc). Lowest prices Marriott site has are EUR 99 (stay for breakfast) and EUR 79 (room only). Do you think Marriott will apply the guarantee and slash 25% of EUR 96, or will they claim that the EUR 79 room is comparable room type and the guarantee does not apply? I read terms and conditions http://marriott.com/look/default.mi and IMHO the case isn't clear, the rules could be bent in any direction. Has anyone used Marriott's Best Rate Guarantee before? Do they apply it only if ther's no other way, or do they follow logic a bit? Our budget is tight, and EUR 96 isn't quite affordable, even -25% will be maximum we can spend... I e-mailed Marriott but the answer was vague of course - they look at it on a case-by-case basis. N.
