My short answer:

NO!

My long answer:

Many people think that if they go directly to the resort or directly to the airline, they will find the best deal. I could see where intuitively, you would think,  “take out the middleman and save”. This is simply not true and in most cases going direct will cost you more. Travel Agents are the preferred distribution channel of all our travel partners. Our resort and airline suppliers don’t want to undercut our prices. Our experience and knowledge give our suppliers happier and more informed consumers. We also cost our suppliers less than managing their own reservation staff or paying a call center to handle their direct reservations.
