We were in cabin 8300 on the Glory. Yes you can hear the chairs sliding around on the lido deck. It's more noticeable on your Balcony than in the room. But will it spoil your cruise, not ours, actually its not any louder or anymore annoying that fellow cruisers moving up and down the halls.
Its not so much the big lounge chairs as it is the chairs that fellow passengers use at the tables. You'll do fine..... it was our first trip so I was keenly aware of every bump and knock. Never can tell when a stray iceburg would float into the Caribbean
