I do both. Never stopped either. Covid was catastrophic for many owners. Could you pay all your mortgages without rentals?
I use a cleaner and a service for the sheets.
If you don't, you can forget ever going on holiday during the school holidays again.
When I had 3 rentals I did 26 loads of washing each weekend. So you need a very good quick machine. Something that takes 3 hours is not going to cut it. And a lot of washing lines / drying facilities. Even if you just do the towels and out source the sheets.
Things to remember:
You can only sell each week once.
You will need spares of everything from loo seats to fridges
3 changes for every bed and some extras.
Buy patterned linens because it hides marks.
Loads and loads of spare china, cutlery.
Pans need replacing annually pretty much.

Buy your beds from the makers not the resellers. I have zip lock beds. Pain in the arse to change but good flexibility. Lasted 11 years so far. But means yet more sheets.
Get interior photos done by a pro. Use the same ones for each website. You'll want 25 per property more or less including bathrooms. My preferred choices are Airbnb, VRBO.
Booking.com was very good for longer out of season bookings but they randomly change things on the site and screw the owner over majorly. They are a scary company to work with. And very punitive.
Get key safes so guests can let themselves in.
Spend time writing guides (multi-lingual) to stop guests ringing you too often. Know how everything works because you'll need to be able to talk through how to restart the boiler etc.
Stay in them for a good before you rent them out. It's the only way you'll work out what's crap/missing.
Mine barely wash their faces in terms of income. But when the mortgages are done it'll make the equivalent of a small salary.
