So, I'm looking at driving into Prague for the beer fest next month, and I reserve a room for two nights downtown. I ask the hotel how much is parking per night in their lot, and they come back with a quote of 900Kc / night (roughly US$ 48). After I peeled myself off the ceiling and stopped gasping for air, I decided to exercise 'The Google' and see what parking looked like in the surrounding area, and most of the places I found came it at around 700Kc per day.

Does anyone have any experience with a somewhat cheaper, yet secure parking lot in Prague near a metro station? Some sort of on-site security is a must. If not, I guess I'm stuck paying the hotel a pound of flesh for a safe parking space for two nights (the train isn't really convenient for this trip).
