It used to be quite common for hotel staff in Prague to demand a payment for allowing a WG up to your room (500 or even 1000 Cz). Not sure if that still happens, as although I visit Prague quite frequently (pandemics aside), I gave up booking girls to come to my hotel. The price for an outcall is way above the price for an incall, it just isn't worth the extra. Beware the outcall agencies, most of whom are out-and-out rip-off merchants, looking to fleece tourists with more money than sense. Some of them have had the same pictures of the same girls up for a decade or more. The outcall indies are better, but are mainly aiming for the higher-end of the market. Incalls, both parlours and indies, are so much cheaper and better value. And Prague is such an easy city to get around, even at night, it is no trouble to get to them.
