I attended Gen. Purpose Rifle, Urban Rifle 1 & 2, & Precision Rifle 1. It's a great school & I believe you'll be very happy w/your training. General notes: Bring sunscreen, knee/elbow pads, & a hat w/a brim, plus a small range bag for ammo etc., & a 20-oz or larger water bottle. Cold water is provided but breaks are relatively infrequent, so you'll bring water to the line. The training is physical; lots of getting up & down behind cover, so if you live a sedentary life like some of us (a-hem! [:D]) you might want to do some walking, stretching, etc.
If not staying at TR, I recommend the Motel 6 in Kerrville. I stayed at a non-chain type hotel briefly on my first trip, but fled due to bugs on every surface of my room. Motel 6 was built in '98, cheaper, clean, modern & comfortable. Have a good 100-yd zero before you go, if poss., & bring a bipod if you use one. (I shoot Highpower competition, so I used a sling for GPR, which worked great.) Don't bring garbage rifle ammo (e.g., cheapo .308 147 gr. FMJ.) You'll be shooting for precision out to 300 yds, although much of GPR practice is at 100 yds or less. If economy on ammo is critical, you can use less-accurate ammo for the short-range portion. However, know your zeros for both types ammo, if you do bring two types!!
Short, light rifles work well at TR. Shooters w/long, heavy rifles tend to re-evaluate their choice after Thunderville. Many vow to sell the big rifle when they get home & get something like a Rem. Light Tactical Rifle. Students deploy & carry the rifle a lot, including crawling & maneuvering through tight quarters in Thunderville. In GPR I used a Win. 70 XTR Featherweight in 7x57mm (similar to 7mm-08) w/a 12.5" length of pull for easier bolt reach, Pachmayr Decelerator pad, bedded & free floated, trigger job, Leupold 2.5-8X VX III scope, & a 3-point sling. It weighed ~8 lbs, & was great. A good, standard light hunting rifle works fine. When I got home, I cut the barrel to 18.5" to make it that much handier, but 20" is a good overall length. DON'T USE CHEAP OPTICS. You need a good scope; my personal preference is Leupolds w/click, not friction, adjustments. (This can be Vari-X III, low-profile "coin click" knobs; target knobs are unnecessary.) Good, tough scope mounts/rings are important; flimsy see-through aluminum rings can cause trouble. Expensive "Tactical" models are not needed but they do need to be durable.
I wrote highly detailed articles (9-12 pages each) on these courses; they're available as reprints at modest cost from Precision Shooting Magazine (1-860-645-8776). They appeared in "Tactical Shooter" (now replaced by "The Accurate Rifle"):
1. "Down & Dirty: Urban Rifle at TR." (part 1 of 2; detailed info on TR staff, facilities, classes, etc.) 3/99 Tactical Shooter
2. "Down & Dirty Part 2" Detailed description of UR1, tells re: low-light training, simulators, etc. 4/99 issue.
3. "TR's Gen. Purpose Rifle" Detailed account of the course, w/info on equipment, drills, etc. 9/99 issue.
4. "Fun in the Sun With Guns -- Prec. Rifle 1 at TR" Covers PR1 but has some useful info for the scoped-rifle shooter. 5/2000
5. "Runnin' & Gunnin': Urban Rifle 2 at TR" Covers UR2 including self-defense from vehicles, etc. 10/2000
Hope this helps!
