Just checked out of Coronado Springs July 19. The tower construction is happening near the front of the resort, so you see it when you drive into the resort, but it wasn't loud or intrusive in my opinion. The room renovations were happening in Casitas and we were in Ranchos 7A so I didn't notice anything with that. Our room location was awesome! We got a renovated room and it was really quiet and super close to the bus stop. The amenities at Coronado Springs will not be impacted by construction.
We went to the main pool almost every day of our trip and it is great! My kids (12 & 9) loved the jaguar slide and the pyramid. I also really enjoyed the food and drink options at the main pool. I love this resort and would love to stay there again!
