I have some contacts at local hotels and have been given clearance to bring in some samples for the sales and marketing team.  Given that most of the work they would potentially send me would be wedding cakes, I'm wondering if I should do a cake tier rather than cupcakes.  Are a variety of flavors more important or the appearance of my decorated cake?  

Obviously, cupcakes would be easier for them to divvy up amongst the 25-30 employees.

What do you think?

Back when I was doing cakes for a hotel, I took in two 6" cakes of my most popular cake flavors (decorated simply, but nice looking) and a small photo album of my wedding cakes.  Once we made an agreement I made up another 8x8 photo album for the sales office to keep on hand for the brides to look thru.

JMO- You are not doing this so that the staff can have a free treat - this is business, and I don't think it is necessary to make sure that the entire staff gets fed. 

Cake for 25ppl?!? 

That's how it works in the city I live in.

there is just one person that takes cake of the wedding, called wedding specialist or catering manager.. It depends on the number of weddings the boom each year. 

I had meeting with just one person, only once with 2. I really don't understand who these 25 people are. I used to work for a 4 diamonds hotel and now I work with them with my own business. 

So when I met up when the wedding specialists to be on their preferred vendor list I brought some cupcakes, 6 with 3 different flavors, a couple of sugar cookies, a couple of French macarons.. It depends on what I had on hand most of the time. 

Hope it helps!
