Limited search capabilities
We have children and any hotel we stay in must have an indoor pool for the kids and a hot tub/whirlpool for my hubby. This app only lets you search by location, number of guests, specific brand of marriott conglomerate, and special rates (ie military or caa members).
Until they add the other search items one can use online or on separate travel apps (that also list all the hotels in the area, btw, not just marriott brands!) then I wont bother with the marriott app. Meaning someone else might get my business.
