Direct answer
Sometimes — if you land before ~9pm and move fast through customs. After that, sleep near the Puerto Juárez ferry and cross in the morning; late-night Isla arrivals are two legs (ground + ferry) and easy to underestimate.
Sometimes — depends on landing time, luggage, ferry schedule, and comfort moving at night. Late arrivals are often easier if you sleep near Cancún or Puerto Juárez once and cross in the morning.
