My 2019 son attended Doyle Academy's winter 5 day camp over the holidays. Thought it would be helpful to post some comments on this and a couple of others.
First and foremost he had a lot of fun at Doyle. The boys worked hard for sure. They are pretty old school down at Doyle - my guy went in very fit but was sore the entire camp due to countless push-ups. That was fine. The instruction was also very old school.
Hitting - Blake Doyle is hitting coach for the Rockies so obviously can add value to an already strong hitter. I won't comment specifically on their hitting philosophy but some of it does conflict with a lot of the latest thinking out there.
Glove work - my son is a MIF/P and I can definitely see improvement there. Blake Doyle did a lot of the instruction here and I can see a solid difference in the way my son transfers - as a MIF that is key.
Throwing - this part was the most old school of them all. A lot of old throwing drills (power position, etc.) which have been completely debunked and will do nothing to improve arm action and potentially make it worse.
Accommodations were at Tigertown - a bit below what I expected for a pro guys but very sufficient as a dormitory. They boys were not thrilled with the food. I think my guy lost a few lbs. from all the training and not enough eating. They ordered Dominos every night because they were starving.
Also note the Doyle folks are religious so for a blue state guy this was an experience.
In summary, good time, reasonable cost but was hoping for more. Perhaps expectations were too high.
Haven't been to IMG Academy so hard to compare the instruction.
Have been to Texas Baseball Ranch (Thumbs up) and Armory Pitching Academy (soon to be Florida Baseball Ranch - Big Thumbs Up!). Both are fantastic but obviously focused on pitching. Both have helped my son a lot.
Happy to answer questions about any of these.
Thinking of options for early August after the travel season ends. Would welcome any input.
