My route trip is Prague-->Berlin-->Vienna. I want to change the route to be Prague-->Berlin-->Paris.

Additionally, I already got my Schengen Visa, but after that I found a good deal in another hotel.

1. Can I change the first hotel I will visit before I travel?




2. If yes, is that going to cancel my visa or anything like that? Also I planned to go to Vienna and go back to my home from there.




3. Can I change it and go to Paris instead?

You can definitely switch hotels or make some small changes to your itinerary. This should not invalidate your visa (but see Andrey's answer regarding some questionable practice by some Schengen countries). Going to a different country could be slightly more risky but it's still generally possible. For example, stopping somewhere on the way, changing the order of countries or adding a new destination to a trip is perfectly OK. By contrast, using a visa for a completely different purpose is not (at least in theory).

Specifically, the rules are laid out in article 34 of the Schengen Visa Code:

1. A visa shall be annulled where it becomes evident that the conditions for issuing it were not met at the time when it was issued, in particular if there are serious grounds for believing that the visa was fraudulently obtained. A visa shall in principle be annulled by the competent authorities of the Member State which issued it. A visa may be annulled by the competent authorities of another Member State, in which case the authorities of the Member State that issued the visa shall be informed of such annulment.




2. A visa shall be revoked where it becomes evident that the conditions for issuing it are no longer met. A visa shall in principle be revoked by the competent authorities of the Member State which issued it. A visa may be revoked by the competent authorities of another Member State, in which case the authorities of the Member State that issued the visa shall be informed of such revocation.

Annulment is more serious than a mere revocation because it's a black mark on your record. It implies that you lied to obtain a visa.

In practice, if you show up somewhere unexpected, say in Germany with a visa for Greece, you might get a few questions about that. If you have a good explanation and all the necessary documents, there is no reason you would be denied entry and/or your visa revoked but if the border guards think you lied to get a visa and you always intended to come to Germany, they can annul it and send you back.

So the answer is not a clear-cut “your visa will become invalid if you change your hotel” but it's not “this visa is valid for anything anywhere within the Schengen area” either. Border guards have to decide whether it looks like you obtained your visa fraudulently and they do have the power to invalidate it if they think that's the case.

In your case, you are still going to typical tourist destinations, you would be entering through the same country as originally planned and the itinerary sounds very similar to the one you submitted when applying to the visa so I would not expect any problem. In all likelihood, the border guards in Prague won't even ask you anything beyond routine questions. If you are leaving in time, the border guards in France obviously have no reason to be concerned either.

Travelers' forums in Russia (for example, this one) have lots of reports from tourists who were notified that their visas were canceled after they canceled a hotel booking in the Czech Republic. There are also a few similar reports with German visas and I never heard of any such occasions with the French.

I also never heard of any occasion when a Schengen country canceled a visa after a hotel was canceled in another country (although, of course, it proves nothing).

Rules laid out in the Schengen Acquis are quite vague in their wordings and are open for interpretation. On one hand, there are references to possible plan changes. On the other hand, the EC made a number of condemnations of the practice called 'visa shopping' when travelers procure visas for 'lax' countries and then go to 'strict' countries instead.

As it seems, some countries, like the Czech Republic, systematically control hotel bookings by foreigners, some, like Germany, perform occasional selective checks, and some, like France, turn a blind eye on all this.

I have also read in many places and I don't know why people are spreading wrong information. It is clearly written here:

A Schengen visa obtained by any of the Schengen Area member countries allows free movement to its holder within the whole Schengen Zone regarding the European Union Schengen members as well as the EFTA Schengen members, up to its validity and timeframe.

and in another place

Can I travel to more than one Schengen country with the same Schengen visa?
Yes, once you are issued the visa you can travel within the Schengen area as long as you don’t exceed the timeframe granted your visa.

The only thing you need to remember is

If the applicant is planning to visit two or more Schengen countries, it is highly recommended to be applying for the visa in the embassy/consulate of the country you will be residing in for most of the traveling days, referred to as the main destination.

It is simple as that. No ifs and buts. The Schengen visa means the visa is for the Schengen area; otherwise it will be called a country-specific visa.

There is no requirement to enter first to the country who issued you visa and hence no hotel change issue.
