Definitely go beforehand, unscheduled if you can. You want to be able to see how things are run when they're not expecting you, if things are clean, horses are in good condition, etc.
And not to sound harsh but your horse probably isn't going to care as long as he's well taken care of, fed and comfortable. Horses aren't sentimental like people are, you just need to make sure he has an adequate standard of care. Check in on him every so often, etc.
