Animal protesters were launched to the floor by security guards after charging through the Marriott hotel and clashing with fuming guests.
The large gang of activists made their feelings known by storming up the stairs of the luxury hotel.
After getting past the guard on the door the group marched through the lobby and through the building with megaphones.

The shocking protest took place at the Grand Residences by Marriott, on Park Street, Mayfair, London, as reported by Need To Know.
Footage filmed by the activists show the security chasing them up the stairs, whilst pushing them and knocking the phone away.
The guard was also seen shoving a protester in a skirt to the ground whilst attempting to get them out of the hotel.
An American guest stopping at the hotel, which can cost upwards of £729 a night, also clashed with the animal activists.
Outside of the building with his dog on a lead and his son next to him, the guest was filmed screaming in the face of one of the protesters.
The guest shouted: “You wake my son up.
“Everytime, he’s right here, you wake my son up.”
The protesters repeatedly chanted at the security guard: “Shame on you.

“Shame on you for what you do.”
The footage was posted on Monday (20 Jul) night, quickly racking up over 110,000 views.
Members of the public were left shocked by the clip.
One person said: “These people are completely and utterly deranged and need to be dealt with asap.”

Another viewer added: “Apparently it’s about the hotel chain refusing to go cage free.”
One other person wrote: “That’s not protesting, that’s trespassing and being idiots.”
One person questioned: “What are they doing in a hotel?”

Another person added: “Lunatics.”
Jam Press has approached the hotel for a comment.
