I have played at the one in Velencia (Forgot the name), and I have played at Conquest. Suprisingly I like HSP the best out of the three.
First of all, if you have been reading the reviews, notice most of the negative reviews were posted in 2005. I'm sure it has given HSP the opportintiy to idintify their flaws and improve on them. I played at HSP for the first time on 1-27-07, and suprisingly, I had a great time. I beleive because of it's popularity, it causes some over population. I will list my pros and cons for 2007. I hope this helps the people that is looking for a field that they will enjoy.
The Fields - There are four excellent scenerio fields (It's hard to chose which one is my favorite)
Safety - People complain that refs explain that before every game the refs explain what the rules are. Beleive it or not, there is always one player that still don't get, so why not drill it into peoples heads all day. Keep doing what your doing refs.
Shops- There shops provide everything you need related to paintball. There shops also provide snacks.
The games should be played back-to-back, rather than play one, then wait 15 minutes for the next game.
Big field, but not enough refs to capture every hit. The refs trying there best though.
Fields are great, but need some paint to be cleaned off the fields.
