Looking for reputable gun ranges in Galveston that are friendly to beginners?

My family and I are taking a small vacation to Galveston in a couple of months, and I was thinking it might be fun to hit up a firing range for a few hours. We don't have any experience shooting guns, and do not own any of our own, so a place that is friendly to beginners would be great. Obviously a place that rents firearms for use on the range would be required for us. Having an instructor guide us through the proper procedures would definitely be a plus. Lastly, there would be one minor with us (it would be my nephew [14], my Dad and myself). I figure it would be a fun experience for all of us, but I'm completely unsure about where the ideal place would be, and have never been to a range before. Was curious if anyone knew of a range that meets these criteria? TIA!
