Are there any agencies in Cuba?
I know Varadero resorts usually don't allow visitors, but if someone books hotels in Havane - would they allow visitors?
Also what is govt stance on mongering there? - Do they support as it this brings foreign currency or do they curb it?
Just need to be careful in socialist countries with dictators (just do as they say)
There are no Agencies period! nothing like that there. Just meet girls on the street or in Clubs. You may be able to bring a lady into a hotel but security may stop you but would probably take a tip to look the other way. Typically the hotel would want you to pay for the lady at full cost.
It's easier to stay at a hotel and rent a house for mongering if you don't feel safe staying in a house. Otherwise just book a house don't waste money on a hotel. That just frees up cash for mongering.
The gvt does not support mongering but does nothing to tourists. Typically it is the lady that needs to be careful and they can be stopped by police and questioned as to why they are with a foreigner but that is very rare during these difficult times.
It is all situational, but generally you can spend time with a lady for between 5k - 10k pesos or 15-30 USD.
It takes time to learn and understand Havana but it really has never been better except that in the past there were many more women around. Back in the day, women where not allowed to leave the country let alone their own province.
