Just went through LIM - twice in the last week. You should also consider how crowded it might be depending on time of day. At the beginning of the trip, we arrived in the morning and it was calm. We ended up walking through the terminal and eating at one of the restaurants to kill some time. On the way home last night, it was the hectic late evening bank of connecting flights and I noticed a line of people at both lounges trying to get in. Probably not good value for your money at that point in the day if you have to pay.
