Quite possibly been asked before so apologies if it has. I've booked a flight + hotel weekend with BA Holidays GLA-LHR with the stay being at the Doubletree Hilton in Islington, 3 guys, 2 x rooms, do I still get my Hilton Gold membership benefits ie Breakfast or because I booked through a 3rd party (BA) do I miss out on these? Thanks for any replies.
