to have somebody over versus to have somebody round/around

[JACEK1]

Hello again!

To have someone round/around = to entertain someone in your home.

1. I HAD the neighbours AROUND for dinner last night.

To have somebody over = to entertain / invite someone.

2. We are having his parents over for the holidays.

Does it mean that in sentence 1 the neighbours came for dinner last night unexpectedly / without being invited over?

Does it mean that in sentence 2 his parents were invited (over) beforehand and when they show up, they will be entertained by the householders.

Thank you.

There is no difference in meaning if I have someone "over" or have them "around."
