Working toward Cenotes
Having your sidemount tanks stay set up is far more convenient. If you can even rent them to start.
If you drop your tanks off to be (Nitrox) filled, say near the dive sites and far from your house, the freedom from shop hours may be minimal. Unless you make two trips or have two sets of tanks. But fill paperwork is simpler than rental paperwork.
ETA: Getting dinner while your tanks are filled won't work if the nitrox banks are empty as it's the end of the weekend.
