Bulgaria in May is one option I'm considering,nothing definate yet.
I commented on your other post but think you'll find JY much better than other companies. Not that I've personally been with anyone else but on my trips others have mentioned they think JY are the best singles company.
From my experience JY seem very organised, they also listen to us customers. eg, On a touring holiday I did one of the hotels wasn't up to scratch and a lot of us mentioned this, following hols the hotel was changed.
