So apparently this mall along with The Galleria Mall are the top two favorites in the Houston area, according to Yelp. I love the fact that they mix high and low end stores to meet the needs of the diverse clientele in the area as well as a variety of stores to meet the needs of all ages. They keep this mall clean. In the food court area I have even seen the floorboards being cleaned.
From between 10 and 20% for Hotels usually as a basic commission - although, on some OTA's they have the option for the hotel to choose to pay a higher % to gain a higher position in listing and search results.
My fee for a custom trip for 7 people would far exceed $100. A travel agent usually does get their fee in the form of commission from hotels, tour operators etc. Since commission on airfare in basically non-existant, there is usually now a fee for an agent to book airline tickets.
