Riverside suites is immediately adjacent, actually above part of the riverwalk. So if you want to be "where the action is", stay at Riverside suites. If you want to be there, near all the bars, restaurants and shopping, it's a great location.
With this proximity comes some negatives. Noise, especially if you are on a lower floor, is unavoidable. Parking and resort amenities are lacking, the building is an old converted warehouse of some kind if I remember, like La Belle Maison in New Orleans, so the room are smaller an oddly layed out.
Honestly I prefer La Cascada, it's not too far from the riverwalk, and have a great rooftop pool and hot tubs, grilles, its walkng distance to an HEB grocery store and other restaurants. Rooms are spacious and more standard Wyndham feel. It's also on the river so you may get a room facing the river but it's the part of the river which is not "the riverwalk", so it's not loud. Last time I was there was in 2022 and got a 2BR Deluxe on the side facing the river, has a nice balcony overlooking it. There's also a public parking garage a couple blocks away you could park for like $6/day (the price may have changed since then)
