Poolio, welcome Us7sail mentioned retrofitting steps when you need the liner replaced, let me just add that steel steps (made out of the same material as metal pool walls) are available they fit in the corner of the pool, if you'd like more info, just let me know and I'll find out who we get ours from and get back to you (* I'm not trying to sell them, just informing that they exist) We install 3 - 7 sets per year, it's not hard to do once you get the hang of it.
If you're not looking at a liner replacement in the near future, the drop in steps are fine as long as you can secure them to the deck (and of course use the sandbags) - though they do tend to be an algae incubator. Again, welcome to the forum, hope that you have a wonderful season using the info you pick up here - Waste
