The way you project your own fears and opinions onto the tourist population is astounding!
Have you ever seen a study or had a conversation with a tourist about their attitudes toward seeing someone carrying a gun?
There are plenty of places in the US with open carry rights where people actually open carry. Some of these places also have tourism. Have there been any reactions by tourists that caused them to reconsider open carry?
Do you think Liberals on vacation have a different reaction than a more logical, Constitution-supporting American when seeing a gun carried in public? If so, do you think we ought to consider outlawing open carry everywhere so they are not freaked out? Do their opinions matter more than those who prefer to open carry?
Do you realize if more than a few people open carry, there won't be a rash of gun owners being "targeted" by crooks, because the other gun owners will likely assist him/her?
Cops carry all the time openly, but there hasn't been a rash of them being targeted for their guns or to remove the threat to their planned criminal acts. Crooks will simply pick a less protected location/group to target.
Do you realize it's easier to draw quickly while carrying openly than concealed since clothing doesn't get in the way?
Have you ever carried a handgun in public, either open or concealed?
Have you ever been in a public place and seen anyone other than security or LE with a gun on their hip? If so, did it freak you out?
It's fine to have an opinion, but everything in your comment is total hypothetical and imagination!! 
This has nothing to do with my own fears, it has to do with image. Consciously or unconsciously people notice things. Some retailers say no guns in their establishments because they don't want that image.
Yes I have had conversations with foreigners who didn't like guns being so prevalent in America. If they saw people carrying it around on their hip they might avoid the area. I am not going to speculate what amount of people would avoid traveling to an area with open carry though because I idon'thave any sort of quantitative data to refer to. Like I said, it is something to consider when it makes up such a huge portion of our economy. If I can find any studies done in other places will be sure to post it here. Maybe a tourist association has already made such a study?
In a crime type situation cops, security guards, and anyone known to be armed is going to be the individuals first target because that is the biggest threat to their actions. A few years back there was news here about a guy who walked up and tried to grab a sheriff's gun. You cannot really compare a cop to a regular citizen when it comes to open carry though, a cop has other weapons, they have body armor and they have training, etc.
Yes you can draw faster in open carry but that advantage is outweighed in most situations by the fact that someone can see you are armed but you don't know when a threat is coming. If I am going on a shooting spree I am shooting the biggest threats first.
Now if enough people open carried then sure, it would be a deterrent, but realistically what percentage of the population would regularly open carry if they could legally?
I don't recall ever seeing anyone besides a cop or security guard carrying in public. I have seen it in private businesses though. It surprised me because I don't see it often but it did not bother me. Most of them were establishments I frequented.
Here is a poll, not significant in size though.

Even though you don't fear guns, is this what you want your community to look like?
