hiding layouts

[Guest]

i have database with two privileges "guest and admin" now for the guest only one specified layouts must be visible and remaining layouts must be invisible so that if visible is pressed hes gets and awkward screen with no access he must see only one specified laout . yes we can create layout by duplicating and modifying and startup with that specified layout but i need alternative

Wouldn't you just go into account management, privilege sets, custom privilege set, and set ONLY the layout you want the guest to be able to access, and all the rest "No Access"?
