We have been to about four different facilities for indoor tournaments. By far, the best play I thought was The Dome in Indiana. The ceiling was high, and they could pretty much play a full field. It was definitely the most realistic besides the turf on the floor. There are almost no ground rule calls due to the larger size of the field. The only strange part was the size of home plate as they used the painted corner of a soccer field; it was large, and the umpires would often call the whole plate.
I have seen college coaches at The Dome, Spano, and GFOD (although we are not sure whether GFOD will be open this winter).
Also, there are a couple of college exposure tournaments that draw coaches. We have been to Sinclair Community College, and they draw somewhere around 10-20 coaches. Game times are important though as most coaches do not show up for late games, and only a few are left on Sundays. They have had this tournament for two years, and they have improved quite a bit from the first to the second year.
I believe there is also an indoor exposure tournament at a couple of colleges, but I can't remember where.
