Yes, you'll need have enough battery to get there or charge before you leave.

You won't get that charge time at home unless you decide to put in a 350 kW charger at your house, which will be expensive.
An 18 minute charge time on a fast charger can support about three cars per hour. There still need to be better batteries that can sustain higher C-rates to make fuller use of the existing 350 kW chargers and future 400 kW chargers and beyond.
For a future, high C-rate battery with 100 kWh usable capacity, 10 to 80% would be 70 kWh. If it could charge 10-80% at a flat 350 kW then that would take 12 minutes. At 400 kW it would take 10.5 minutes.
Battery swaps can currently be done in 6 minutes. Swapping in a 100 kWh battery charged to 90% in 6 minutes is equivalent to a flat 0-90% charge curve at 900 kW:
