The area of the zoo and the number of animals are impressive. But crowds of people, huge queues to shops, restaurants, toilets or other facilities inside, such as an aquarium, effectively spoil sightseeing. Several (very nice) playgrounds. Too much for one day, not only for a 5-year-old but also for parents. Six hours with a break for food and playgrounds.
Tower vets are so helpful and friendly. Make you feel at ease. They always give you the best advise. They make sure your animal is cared for in the best possible way. Would highly recommend.
