There really are not too many and they are 'partial' takeovers. So there are still rooms. You just kind of need to know the groups as I dont think the resort posts them. There really is only one I know of that takes over the entire tower (ocean, garden and Temptation suite rooms still available) and this thread is about that group. There has been a mocha takeover group which instead of 150 rooms is more in the mid double digits but I thought that group in 2018 was in the fall and haven't heard anybody talking about them this year so maybe they were not able to return (there was some damage done to the resort with that group in 2018).
