To each their own, and God love ya if this is your thing. Split stays suck. Full stop.
Arrive at Resort A, unpack suitcases and owner's lockers, and load up the fridge and cupboards with groceries. Get everyone settled in, and then just a few days later, pack everything up for the hotel transfer. Be out of Resort A by 11:00 AM. Go about your business and then go to Resort B, where if you're lucky, your new room might be ready before 4:00 PM, or later. Then, retrieve all your stuff to unpack again for a few more days. Thanks, but no way!
