Prague Travel Checklist
Some of the stuff on this list is so obvious that you'll think you'll never forget it. But enough people have forgot that I wrote a page that you can more or less use as a tick sheet for the most essential items.
The Checklist - General info
Visa collected (if required) before travelling.
Flight/Train Tickets or reservation numbers.
Frequent Flyer card.
Travel Insurance (if required).
Passports have at least 6 months validity left on them i.e. if you arrive January 1st, the passport must not expire before July 1st.
Children aged 15 years or more must have their own passport.
Private healthcare details and cover.
Sheet of paper containing hotel address and duration of stay plus home address and placed in each piece of luggage.
Mark each piece of luggage that it can be clearly identified as yours. Personally I put medium sized coloured cord on the handle as it cannot be mistaken as can a side sticker for example.
Description of your suitcase in the event it is lost. Include size, colour, make and/or identifying marks. You can even take pictures to be sure.
