Is a weekend trip really free?

Yes, for two of you, with as much detail in it as you like. No card is needed to sign up.

Can I reuse it for the next weekend?

Create a new holiday. The free tier covers one, so beyond that use a Holiday Pass or Unlimited.

Is it overkill for two nights?

It takes a couple of minutes to set up. If all you need is a shared note of the train time and the dinner booking, it does that too.

Plan a weekend away in about five minutes

A weekend away does not deserve a project management tool. It deserves about five minutes of thought, written somewhere everyone can see it.

A two or three day trip with a handful of plans fits entirely inside the free version.

Two dates and you are set up

Enter Friday and Sunday and you get Friday, Saturday and Sunday. Add the four or five things that are actually happening and the weekend is planned.

The bits worth writing down

What time the train or flight is, and what time you need to leave for it
Where you are staying and the check-in time
The one dinner you booked, and the name it is under
Whatever you need to remember to bring

Genuinely free at this size

One holiday and one invited person, with no cap on what you put in it. A weekend for two never touches the limit, and if a third person needs to be on it, unlocking is £6.99 once with nothing recurring.
