Start by making a specific list. Is that 10 full days on the ground, or does that include landing and heading home?

Map it to see how far each place is from the next place. No sense spending all your time on the train.

You will be surprised to learn that you can't do it all in the time allotted.

If you haven't already, book an open jaw ticket, so you won't have to backtrack.

That's a start.

Owww! Do you actually want to see anything in the cities mentioned? Or do you only want to rush through so you can tell people you've been to all those places?

With travel time between each city, plus checking out/in at hotels, you will only get about a day in each place for sightseeing. If that's all you want, fine. Some people actually like rushing through and doing speed-sightseeing. And some people enjoy the travel part (being on trains or driving) more than the actual destinations. If that's what you want from your trip, then it's perfectly fine. But, if you actually want to experience your destinations, you will not have enough time.

Is there any reason for these specific cities? Anything you actually want to see in them? Start by making a list of things you really, really, want to see in each city. If there is any city on your list where you can't come up with something you really want to see, then drop that city from the itinerary.

We have a wedding to go to in sebersdorf, would like to see Venice, vienna and saltzburgh. Thanks for your help

10 days include travel dates

So you have 8 days for a wedding and 4 other locations? You'll have about 1 day in each town. Are you sure you want to do this?

Wedding is one day in sebersdorf

OK -

Let's try to do this is a logical way:

Day 1 Arrive Vienna - 1/2 day sights
Day 2 Vienna sights
Day 3 train or drive (2 hours) to Severdorf wedding
Day 4 train or drive to Salzburg (4/5 hours)
Day 5 Salzburg
Day 6 Salzburg to Venice (6 or 7 hours)
Day 7 - 9

Sorry

Day 7 - 9 Venice
Day 10 Fly home

So you have 3 days in Venice (quick but doable), but you have 1 day in Salzburg (need 2 days in town and 1 in the countryside) and 1 plus a little in Vienna (IMHO you need at least 3 - 4 is better)

Also you will pay a large drop-off fee to rent in Austria and drop in Italy. Train may be a better option - but don't know schedules details - you can check them on bahn.de (for times - not prices).

>>10 days include travel dates<<

>>Wedding is one day in sebersdorf<<

As others are trying to tell you this really isn't doable in 10 days.

10 days minus 2 days travel to from Europe (BTW where are you flying in to and out of?) = 8 days

8 days minus 1/2 your arrival day (jet lag/transfers/checking in) = 7.5 days

7.5 days minus 2 to 2.5 days for traveling between your other destinations = 5 to 5.5 days to see four major cities AND attend a wedding.

And IF you must travel back to Vienna or wherever you are flying out of - minus another full day.
