The details that make a stay easier
Where to eat. Mi Tierra Café y Panadería at Market Square for lively Tex-Mex and a bakery stop; Rosario's in Southtown for a Mexican dinner; the Pearl's restaurants for anything from a casual lunch to a booked dinner. Leave one morning for breakfast tacos near your first stop.
A big day out. Give a big attraction (the zoo, Six Flags Fiesta Texas, SeaWorld, Morgan's Wonderland) its own day. Natural Bridge Caverns routes are steep and wet, and strollers are not allowed on tours.
Getting around. A car is practical when your plans include Schertz, several parts of the city or a day trip. Rideshare suits a single dinner out; for transit, use the VIA trip planner with your exact start and end points.
The weather. On hot days, put garden walks and sightseeing early, carry water and save the afternoon for a museum or a rest.
Reserve the important parts. Alamo Church entry, your cavern tour and any meal or show you would hate to miss.
