I booked a standard room and got the Giraffe and ostrich trail. It was an ok view, certainly better than I expected but would not have been pleased had I paid for a better view.
Really, there are so many different vantage points in the hotel that you'll enjoy going to different spots to view. At 5pm I did enjoy watching four beautiful giraffes munch just outside my room. It would have been perfect if the lady with the Long Island accent had only talked on her cell phone INSIDE her room and NOT on the balcony where half the building could hear her.
Enjoy, I had a great stay there!
