Design for cold hands, a phone in one glove and a connection that keeps dropping under the tracks.
Most of your traffic is mobile, and a meaningful slice of it is mobile in bad conditions. Tap targets need to be generous, the phone number needs to dial on one tap, and nothing important should hide behind a hover state.
Carousels, multi-step accordions and tiny toggles all assume a steady hand and a patient user. Neither is available on a windy corner in Logan Square in January.
Weak signal punishes heavy pages hardest. Text and the booking path should render first, before hero imagery finishes loading, so a patient can act while the rest is still arriving.
Test on a real mid-range Android phone over cellular data, not on office wifi with a new iPhone. The gap between those two experiences is where bookings go missing.
