If I buy Houston CityPASS online today, when does the 9 day valid period begin?
Purchase a booklet today and begin use on any day from now until February 29, 2012. E-tickets may be purchased up to 90 days in advance of first day of use. Houston CityPASS tickets are valid for one-time use at any time over nine consecutive calendar days, beginning on the first day you use your ticket booklet. If you start at the Space Center Houston on Monday, you have the rest of that day, plus the following eight days to use your other five tickets. The first attraction you visit will stamp or scan your booklet, establishing your 9-day valid period.
