Option 1: Taxi (simplest, no app needed)

• Where to get it: Follow airport signs for the official taxi stand outside baggage claim.

• Where to meet: Use the airport’s designated rideshare pickup zone (the app will guide you to the correct door/letter).
• Time: ~25–45 minutes

• Step 1: Take METRO Bus 102 (Bush IAH Express) from the airport to Downtown Transit Center
• Time: ~50–75 minutes (service/traffic dependent)
• Step 2: From there, either:
• Walk ~10–20 minutes to Marriott Marquis Houston, or
• Take a short local bus/rail hop depending on timing and your exact stop.
• Total time: ~75–110 minutes (varies a lot by wait times)

Option 4: Rental car (best if you’ll be driving a lot)

• Time to hotel: ~25–45 minutes, plus pickup time
