Welcome to FlyerTalk,

Whether you could identify it without a doubt or not, this is par for the course when dealing with "opaque" booking sites. And in going for the $30 savings, didn't you lose any Starpoint-earning benefits? And maybe other SPG benefits?
IIUC, LastMinuteTravel.com was the competing website.
Did you check LMT's sister site
www.EasyClickTravel.com to see if it was offered on there? That site is NOT opaque. I see that ECT.com has the
Sheraton Mission Valley San Diego Hotel tonight for $149.00 including taxes and fees. It's a package that includes "Continental Breakfast." SPG.com also offers a room with breakfast for $179 + tax = $201.50. They might argue that the breakfasts are not the same. BAR without breakfast is $159 + tax. It's a
potential BRG opportunity, if anyone's interested.
