We tried in July - we could link our
UT reservation to the
Budget website, but we couldn’t link our FB number to it online. We chatted with Budget and were told that would mean modifying a third-party reservation, and they couldn’t do it. So we ended up going to the counter in the terminal. Fortunately, the line was almost nonexistent, so checkin didn’t take long. We did not get to choose our car. BTW the other times we’ve rented from Budget at MCO, via Costco, we were able to link our FB number and go straight to the garage, but our car was assigned, we had no choice.
