We like Mara alot and we are very picky about such places. Most are too crowded, noisy, etc. The food is quite good. When we eat at Boma or Jiko we stop by and pick up some zebra domes and a chicken sandwich on pretzel bread for later.
If you have no plans for Jiko or Boma, I would say, yes, Mara is worth the trip to check out the Lodge. More accurately, the Lodge is worth the trip and you might as well have lunch at Mara. AKL is the most beautifully themed resort at WDW. Be sure to visit the gift shop. It's the best on property.
Another option would be a late breakfast at Boma. We are eating there at 10:45 am on our upcoming trip.
