I've never attended a carnival so far especially since they are not organized in Romania. But they always seemed at least one level higher than festivals which even though have things in common, the audience and activity will always be bigger and a lot more imposing on carnivals.
I suppose every country has their own traditions and customs, sounds like Romania has your own version, you going to try get to one one day?
Absolutely! I was actually tempted by the carnival from Venice which will happen soon but didn't find the right team to book our flights as everyone has other plans that period
