Sorry to be so late in posting, as I know you've already made most of your plans, but I just came across your post and wanted to add some alternative ideas. As a Hyatt Platinum, you should consider enrolling for the Diamond Trial upgrade discussed in this thread:
http://www.flyertalk.com/forum/hyatt...-2009-a-3.htmlIt has recently been reported that the enrollment period has been extended to 9/18, so call
today and get upgraded to Diamond using offer code
2DTRIAL2 That will give you Diamond status for the next 120 days and, if you have 15 qualifying nights during that time, retain Diamond status until 2/2011! Using the VisitSanAntonio.com coupon code (SAVWEB), you could stay at the Grand Hyatt on the Riverwalk for about $112/night with free breakfast buffet for 2, as a Diamond get access to the Grand Club and (as we have experienced) possibly an upgrade to a suite. (Use Offer Code G2 for 2,000 bonus points.) As a convention center hotel, it may not have the charm of the La Mansion, but it's a very nice, new hotel located on the Riverwalk.
Also, Sea World
willbe open on Fri., Oct. 2, if you really wanted to go there. They may be starting their Halloween celebration that weekend. The Hyatt Hill Country is very close by and also has offer codes on the Visit SA website. It is an older property, but might give you a sense of the Texas hill country that you wouldn't experience downtown. Consider splitting your 4 night stay for a taste of both worlds. Use offer code DEL5K for $150 food and beverage credit along with 5,000 bonus GP points and G2 offer for an additional 2,000 points.
