Definitely agree that some of the "enhancements" have made it more difficult for me to find some of the things I'm looking for. Maybe I haven't given it enough of a chance but that RoomKey pop-up is annoying as <insert expetive here>. Why not let me decide if I want to compare competing properties in a city? Why even offer me that option? If go to the Marriott site it's because I want to book a Marriott property - not some competitor. If I want SPG I'll go to the SPG site. If I want Hyatt I'll go to the Hyatt site. I know the "trend" is for brand specific sites to offer you comparisons so you don't leave their site to check out the competitors but IMHO it would be better to have a button/option to compare prices rather than just have that dang pop-up come up everytime I go to check a different Marriott property in the same city.
Sorry for the venting - I was making several reservations for Marriott stays and that annoying pop-up started to get on my nerves.
