Yes the peak of the Russian invasion was about 5 years ago when it seemed that they composed perhaps 25% of visitors to Pattaya and the Sansuck attracted quite a few, although as catawampuscat says they only stayed within their own groups, not like aged gay farangs like me who lusted after any young Asians boys who were there.
I remember a conversation in my hotel I had with a str guy who had tried a few times to engage attractive (for him) Russian girls - he never had any success. There were also many family groups enjoying an exotic holiday. They must miss that opportunity now.
I’m in Pattaya in 3 weeks and will visit the Sansuck which I’m sure will be closed, to reminisce about times gone by.
