Searches for exotic hadrons have taken on a new urgency in recent years. Studies of B->DDh decays stand to make a great impact on this exciting field, providing sensitivity to the spectra of conventional charmonium or open-charm resonances, as well as possible exotic states. Only two published studies of amplitude structure in these decays exist, neither from the LHC. I will present the first model-independent and model-dependent analyses of resonant structure in B+->D+D-K+ decays using LHCb data. Only charmonium states are expected, and structure appearing in either of the DK channels would be manifestly exotic and would constitute the first sign of an open-heavy-flavour exotic hadron.
