Day out with Thomas in Austin, Texas - Where to Stay?

[ChefGirl]

Hi, DH and I plan to take our kids to the Day out with Thomas in Austin, Texas in about 2 weeks. My kids are 3.5 and 1.5 of age. We like to get a suite with separate bedrooms but close to the convention center. We plan to get tix on the day of the event since they were sold out of the time slots that we wanted. Anyway, does anyone have any suggestions on where to stay that weekend?

Thanks a lot.
