Totally worth it for us!

It's really not that many additional points...
Other perks you didn't mention:
- Daily mousekeeping, including nightly turn-down
- You check in at the concierge desk in the lounge while sitting down in a comfy chair - no standing in line downstairs
- Concierge staff will make your ADRs and other reservations for you
- I think we had better toiletries, as well, or at least there were additional toiletries we had not received before (solar gel and something else - mouthwash maybe?); not a big perk, but I did notice it
And yes, having food and drinks available is a great perk. No need to by the expensive mugs at Mara - just take a few sodas/milks/beers back to your fridge. We also had breakfast in the lounge every morning, and the appetizers they serve at dinner were very tasty!
