How many Lev would I need for a week

If you want to do nothing, I  guess it would cost you nothing...

if you want to eat McDonalds every meal I would say 3x20 Lev = 60 Lev per person per day.

I think the local pension is around 200 lev a month (may be wrong) so the locals get by with 50lev a week..

It depends how much you intend to drink while you're in Sunny Beach! This is a forum for expats in Bulgaria full-time, not holidaymakers, so you may get answers that fit your situation better on a holiday forum.

Have a great time!

I'm flying back to the uk next week for a funeral in London, how many stab vests should I take, half bored.

How long is a piece of string? It really does depend on what your habits are? You will need a lot more if you are going to have meals and drinks at a 5* hotel opposed to a food stand by the beach.

What do you plan to do? Sight seeing?
