I would like to know if there are any camp grounds close to Tihany and how much a pitch would cost and or if they have any camp cabins email@example.com
I don't know camping in Tihany - but there is one just opposite in Szántód; you can cross the lake by the ferry.
On the northern shore, close to Tihany is Balatonfüred; here you find probably many campings, ie. the linked below. From Bfüred you can take a bus or a boat to Tihany.
