I have to say I found it surprising that you met two girls ALONE, at the hotel bar and then at the other bar the next day. This is not typical for any country, maybe in Romania it's different? Usually only prostitutes or quasi-prostitutes would go alone to a bar.
In Bulgaria, for example, girls always roll in groups of 2-3 at least, and at the clubs it's even groups of 7-8 or so, due to the bottle service phenomenon. Almost all better clubs now have "reserved" tables only so if you want a spot you have to buy a bottle, and obviously two girls are not going to drink a whole bottle so they team up with friends (and often guys so they can pick up the tab). The good thing is things are pretty cheap in Bulgaria, including bottle service.
Re: Black Sea resorts in Romania, they are no good. Best one is Mamaia, Constantia is just a port/industrial city. Most Romanians drive down to Bulgaria in the resorts around Varna (just 100km or so from Romania) or around Sunny Beach (a further 100km down the coast). Sea water is noticeably colder in Romania, beaches are not as nice, not many good hotels, etc. Of course, people with more money go to Croatia, Turkey, etc. but Bulgaria is the closest and cheapest beach destination for Romania.
