Afternoon all,
1. Weather - second this. While it's certainly never 100% accurate, having a vague idea what the weather might be like each day is super useful.
2. Meetings - I hate it when people put last minute meetings in my diary at work that I have no idea what they're about and have no time to prepare. So I'm always grateful for the ones I do know about in advance!
3. Trip planning - whether it's a small day trip to a full on holiday, knowing and planning as much as you can for a trip is super helpful for me, especially as a mostly solo traveller. The thought of not knowing what I'm doing and just winging it fills me with dread!
