Interesting thread and looks like a good idea for some fun with amazing looking girls.
One other factor that needs to be considered in terms of the prices is that the local currency has nosedived against GBP (as well as USD and EUR) over the last few years, for various reasons. For example, you got around 13 Hryvnia (UAH) for £1 around Christmas 2013, whereas now you get around 32 to the pound.
Although this is not always reflect in travel prices, it makes it much cheaper to be in the country and to buy goods and services there. Also Ukraine has had economic problems for a while and the prices were lower than the UK for many things before the latest currency shifts. To give further context, the average salary in Ukraine in July 2016 was $188 per month (USD to UAH conversion rate at the time)
Thanks to the OP for the post, everything he says sounds credible to me (I also have some experience of that region) and this could be a great opportunity to punt some of the hottest girls in the world, at decent prices (even with the extras).
