I picked up an exchange into a 2 bedroom/2 bath unit at Maui Hill back in 2012. I LOVED it. Not fancy, but quite roomy and comfortable. Loved the location, too. It's still in Kihei, but almost Wailea. Makena beach doesn't have the best snorkeling, but there is great snorkeling all around the South side---and much of the West side, too. If you'd like to see what our Maui Hill unit looked like back in 2012, it's in this blog. Our unit was a little ways up from the pool and ground level, too, and we had a bit of a distant ocean view. I have 3 other blogs of Maui with lots of snorkeling (look at the labels to the right and click on Maui if you'd care to check out great snorkeling. I was with my sister when we stayed at Maui Hill and she's a non-snorkeler, so I had to curb my snorkeling that trip).
