We visited The Island at Lake Travis a month after the 2021 winter storm in Texas. Unfortunately this meant the pool & hot tub were closed. The restaurant had sporadic hours as well. With the nearest grocery store ~15 mins by car away, that meant we had to be prepared to cook entirely for ourselves. The beds were very uncomfortable in our unit - squeaky and extremely soft mattresses and definitely needed a box spring in the main bedroom. The kitchen was well-outfitted with equipment but had absolutely nothing available - not even olive oil, butter, or coffee - again, we had to make sure we brought everything we could possibly need for food, seasonings, cooking, etc. Our unit had a few games as well as limited smart tv features.
Elevators worked fine & generally available, but the building is primarily designed to access facilities using the many stairs - this made navigating with a stroller very difficult. Parking was fine & the lot is very well lit. Tennis courts and shuffleboard are available but (perhaps post-covid) it might be nice to have the ability to borrow equipment rather than bring absolutely everything on your own. There are a few nice hiking spots within 20 minutes drive but unfortunately many of the nearby & closer beaches are closed for private neighborhood use.
The balconies are lovely and large, and offered stunning lake views. I could see that for a condo owner, this would be a very nice place to visit if you keep what you need on-site. For just a few days, however, at the price, I would rather go to a place with more amenities & on-site activities (with equipment) - something that I know is available at other similar resort destinations.
