No-ads will work during the whole game in all your hotels. 
Marketing Expert and General Manager will work forever in all your permanent hotels, but they won't in the weekly Event Hotel.
The Event Hotel has in-app boosters (VIP pack and Boosters 1, 2, and 3) which are different from the purchases in your regular hotels because they are designed for the event mechanics. Since each event offers a different reward, each event will have its own purchases.
