What size beds in an STR?

[Alison Pidgeon]

I am new to the STR game and have purchased my first 2 BR condo. The bedrooms would both fit a king size bed. Do you think this is the best option? Or should I have 2 full or twin beds in the one bedroom? The property is within walking distance of a children's museum, so I am thinking it might attract families with kids. TIA!

We do all queens for simplicity (all queen sheets). And the rooms, although they could fit a king, are not that large and might feel cramped.
