I attended a convention at the adjoining Adam's Mark hotel but headed over to the Westin for a couple of functions. The Westin is also connected to the Adams Mark by a long, glass walkway making traveling between the 2 hotels a breeze. The Westin seems to be much more lavish than the Adams Mark and quite a few of the rooms on multiple floors overlook the galleria and ice skating rink.
The Westin has many conference rooms available and were very hospitable having coffee, tea, honey, water, etc available to guests. The conference rooms were uncomfortably hot even though the weather outside was hot, sticky and muggy. Other than this slight inconvenience, I would stay at the Westin anytime, especially with a room overlooking the ice rink.
