Please help. Need advice 😒

So me and my hubby are going to the Emerald Isles this weekend for like two nights. We really only need a single bed you know what I mean. And the travago and booking gives me like all these king size amd double beds...I dont know what to do. Can you not reserve one that I want? Would it be better to just find a hotel when we get there? Smh :/ I dont know I need help. Advice!?!?!
