We just got back from The Grove and really enjoyed our stay! The resort is fairly small, but a little confusing to navigate on the inside (it's much easier to find your way around by walking outside). The waterpark area is fantastic and kept my kids (17, 13, 11) busy all day. We did have trouble finding lounge chairs mid-afternoon, but could always find a couple together. They have cabanas to rent, but we didn't do that so I'm not sure the cost. One cool feature is that they will deliver food/drinks right to your lounge chair. You can place your order online and it shows up about 20 minutes later. Of course, the food isn't cheap (typical resort prices- $8 kid meals, $15 burger and fries), but the convenience factor is quite nice. There are also quieter pools which didn't have a big crowd any of the days we were there. The arcade and glow golf kept our kids busy for an hour or so and is a rather large area. We enjoyed the restaurants and bars throughout the property and it there is a small store on property that has a nice deli/bakery/ice cream, basic grocery and hygiene items, as well as some souvenirs. We also used the onsite shuttle one day to get to Disney Springs (drops off at the TTC). It is also super close to a Publix which was nice because we ate a lot of meals in the room. Another nice amenity is the parking garage is inside the resort so you can park on the same floor as your room. This was wonderful when loading and unloading luggage and groceries.
On the con side, the resort and parking fee add quite a bit to the nightly cost ($30 resort fee/ $15 parking per day). Our air conditioner wasn't working the first day we were there, but they showed up quickly to try and fix it (it needed a part so we had to wait until the next day- no moving as the resort was fully booked). It's not super convenient to the parks if you don't have a car. It was about a $25 Lyft ride back from Disney Springs. They seem a little short staffed in the customer service department. We often had to wait on hold for 5-10 minutes when we called the front desk or concierge.
Overall, we really enjoyed the resort and our stay and would definitely consider staying there again! Plenty of room for our family of 5 in a 3-bedroom unit. Just for comparison, we have stayed at WBC twice and really liked it, but would choose The Grove over WBC as the amenities are similar but the price ismuch less.
