I would be okay with once a week, or perhaps once a fortnight.

Sprint planning sessions can be hard to get everyone engaged, but it isn't impossible. Retro can be remote, the biggest issue has been, is, and always will be teams that have no control and are dependent on other teams to do anything, don't write their own tickets and don't have an easily viewable plan that they can work towards.

Location has nothing to do with that.
