Those pools are fun! I can see Mo having pool parties already.
For sure, make sure the ground is level. Sand seems to do well to even out a spot.
Some of them come already with cover,pump, and accessories. You can buy kits.
This is one where you need to put chlorine in right? If yeah, it can be annoying to keep them clean (bugs, leaves, dirt). I got into the routine of skimming it every night, then put the cover on for the night.
Oh, just a thing I thought of: if you get the pool, it might be a good idea to have a policy of sorts where the kid(s) or whoever uses the pool has a shower before getting in. They can get mucked up very easy.
If you find a good spot for it (not under a tree or where things can fly in or too much wind), it should be easy as pie.
