At name schools, even a brand name teacher can be avail for this type of instruction during the course of the school session. Again, demand will be high and the price will rise accordingly. Another important question to ask is what the fees are and what they include. Some include lodging and meals. Even commuter rates may or may not include meals, so you'll need to find this out.
Some schools have on-site accommodations, while others have arrangements with nearby hotels.
It never hurts to inquire. If you are attending a golf school as part of a vacation, you will need to narrow down the field yourself, and make the arrangements to attend the school, as travel agents do not handle them. Whatever your expectations and needs for golf instruction, you're bound to find a golf school that's right for you. A little time spent researching different schools and asking about particular programs you're interested is all it takes. As with any golf instruction, don't expect miracles or quick fixes.
