The hotel block options are all in downtown Houston, so don't forget to stop by Flying Saucer and grab a cold one! They have a great craft beer list and an outdoor patio. You will find many selections from Kyle's beer distribution company, Flood Distribution.
Buffalo Bayou Park is a great place to take a stroll, a run, or to bike (there are rentals for cheap!) on a nice sunny day. Make sure to stop by the installation at the Buffalo Bayou Park Cistern, it's fast and quite beautiful.
