Yes, a lot. Tskaltubo has been created by planned economy - most Soviet people never chose to go to Tskaltubo, they just had free travel vouchers given by the Soviet state, and they were happy to go from their grey industrial cities to the town with lush subtropical vegetation, mineral springs, pompous architecture.
After USSR collapsed, there were almost no vouchers + economical crisis all over ex-USSR + borders got open for people to travel abroad. So Tskaltubo lost a lot. But some cities benefited, like a city Batumi, Georgia on the border with Turkey which was closed in the Soviet time. Now, Batumi is thriving.
Thank you!
