Is a sandals butler worth it?

Planning on our HM to Sandals Grenada.

We’re stuck between a basic room, which we can stay at for around 10 days within budget. Or a butler room, which we would only get 6 days at.

I’m trying to see if it is more worth it in others’ opinions to stay longer in a basic room or have a shorter stay in a nicer room with a butler. I have heard the butlers are very convenient as far as making reservations and reserving beach chairs, but besides that, we aren’t too pressed about getting drinks and food whenever we want from them. I also was considering a club level room as an in between to have some concierge services but I couldn’t find much about what that means and how it improves our stay. Would love to hear any opinions! Thanks!
