What options do we have to go to scenic places in the delta by boat from Tulcea?
There are passenger ferries going from Tulcea through the Delta along the Danube's three main channels till the sea, with stops in the villages along the way - although it's possible they won't run on Easter Sunday (May 5).
It's also possible to hire boats of various sizes.
Will there already be tour operators working?
There are at least a few Romanian travel agencies with "Easter-in-the-Delta" offers.
What kind of accomodation will be available outside Tulcea in the delta?
There are pensions/guesthouses (ranging from actual homes to small hotels) in nearly all the villages in the Delta.
Try to book rooms in advance, for local tourist it's an increasingly popular Easter destination
