The gardens are beautiful during any season, and do deserve to have a share of the spotlight. As PeteB has said, a quaint little English tea hatch by the conservatories would be simply marvellous!
I would love to sit in a Tea House, enjoying a drink, looking out over the most beautiful, landscaped Gardens I've seen. In Summer, it would be truly bliss.
When I visit the park with my family, not everyone makes use of the rides & attractions. My mother, for example, would enjoy a nice brew in these surroundings, rather than the main attractions, simply because she likes the more quaint things in life!
The gardens will be maintained for many, many years to come!
