Is this something to be worried about

[Worktrip23]

A is 27 and B is 33 B has invited A onto a work trip and they are sharing an apartment 2 bedroom one bathroom would you find this weird as some people are I personally don’t have an issue with it but then again I’m not going on the trip they are male and female if it makes a difference

Which is male and which female?

They’ll have separate bedrooms, why would it be any different than staying in a hotel? If this works out as cheaper / more convenient / more sociable and enjoyable than a hotel then it seems perfectly sensible.

Who would worry? Are we discussing from the perspective of A's or B's partner, or is there some other unspecified worried third party? What's the context?

There's no situation in which this scenario would worry me, but context is key.
