I'm visiting my parents in Spring, TX but got my tickets at HOU and not IAH. I'm from Philadelphia region and it's simple to hop an uber to train and get to PHI but Houston doesn't have the regional rail infrastructure that South Eastern PA has. Is it easy to het uber/lyft from IAH that far north or should I get a cab or something? It's too far for my retired parents to drive these days and they don't know the roads as well. Any recommendations would be appreciated.
