Start off by knowing this is a timeshare. We are Wyndham owners and have been time share owners for over 20 years. You can always say no to the owner update (if you are an owner) or to the sales presentation if you are new. They will pressure you into going, and depending on the situation you may be "required" to go, but just be firm if you are not interested in purchasing. I went to the owner update to get the valet parking for free and it was not high pressure, unlike some other ones I have been to. The staff was cordial and respectful of my families time.
Now the resort/hotel/condo itself is what I rated here as 5 stars. I give the location a 4 because it could be closer to the main riverwalk area and it would be way more convenient for walking in the hot summers. As it is there is a free shuttle service provided, but it stops at 5 pm so you can't use it after going to dinner or to the bars. While we were there a dinner/night time uber from the riverwalk was about $7.50 and scooters would be about the same. There is valet parking with unlimited in-out privileges, but driving to the riverwalk to then pay $10-$25 to park a little closer is a waste. The part of the river it is on and the grounds are beautiful though, just not quite as convenient as it would be if it was 1 or 2 blocks farther north on the river.
The accommodations were just above average for a Wyndham. We had a 2 bedroom presidential which had a king bed master suite, a double queen room, a second full bathroom, living room with pullout couch, and a nice kitchen and dining area. The presidential distinction means we got a balcony with a river and downtown view and possibly a slightly larger living area. We had no complaints with the room, but it is also not as new as some other Wyndhams. Not old either so it works great.
The staff (not counting the sales/owner update) was always super friendly and they had special refreshments or food available almost every day we were there. We visited the other Wyndham timeshare that is right on the riverwalk and it smelled terrible outside the front door and the staff ignored us and even gave us some strange looks while we waited for the shuttle. The La Cascada staff was not like that at all. They always smiled, said hi, answered questions, and overall were great.
