Not really for me. I've been 4 times in 10 months.
Lucky for me I'm in Florida so it's easier for me to travel to SA.
And once I'm there, I never spend that much. My gf (from Ica) is pretty frugal and laid back. She's happy just strolling in the parque or hanging out at her aunt's house. We always take combies and buses in Lima. Once in a while, we'll hit Norkys for some pollo a la brasa. I think it sets me back about 45 soles ($15).
Then when we're in Ica, it's usually off to Huacachina and sandboarding on those giant dunes. Again, a cheap date.
I never feel the need to spend a lot of money and be extravagant.
