I try to stay away from giving "five stars" but it was hard to find any fault with the Hyatt Lost Pines. It is truly a resort, offering nearly hourly free activities (animal meet and greet, kids crafts, outdoor movies, smores, stargazing, etc.) and numerous add-ons (archery, golf, horseback riding, river floats, etc.). The add-ons are fairly limited with young kids (5,7) due to age restrictions (check before booking if you have young kids), but we took advantage of many included activities with one add-on night hike. There are several restaurants on-site which were quite good. Every encounter that we had with staff was positive - all very friendly, greeting you first and being helpful with a smile.
Our boys couldn't pick a "favorite" of the trip until pressed, and then it was the pool and lazy river (which I have to agree were my favorite too). They have poolside service (drinks, bar food) which is a plus - however, they could do better cleaning the pool area, by the afternoon it was quite littered with cups, trash, etc. - I fault lazy customers but still...).
Yes, being "captive" makes it a bit on the expensive side, but there is a huge plus in not having to leave the property - treat it as a destination vacation. Wish we had thought ahead and stocked up on water, drinks, snacks, but we will do so next time -- as I can absolutely see us making Hyatt Lost Pines an annual get away.
