It looks like a new branch as the website isn't up and running yet, so of course you won't know for some time how successful it is and whether it will do as well as Tanya's Travel in other cities. However, it's a very busy sector with a lot of opportunities. In spite of the world recession people are still travelling for business and leisure, and this is especially true in the US where it's common to travel a lot by plane within the country, and flights are often cheaper than in, eg, Europe.

The site preview looks attractive, and you can see the company is promoting travel that always remains popular, such as trips to Disneyland. I also see there is a large section for cruises, which is another very fast-growing area - lately it seems like almost everyone you meet is going on a cruise.
I have one suggestion for the website - the company should get a proofreader to check it. For instance, 'Your on your way' is incorrect - it should be 'You're on your way' - and there may be other errors too.
