Gonna give you general travel tips just in case you're not doing this already.
Bring your most important things in hand-luggage, in case main luggage is lost or delayed.
Give yourself 2 hours spare time on either end of your flight(s) and changes to allow room for queues and getting lost. Get a SIM for your destination/switch internet and roaming off entirely.
Only use wifi in hotel/venues.
Print off maps to the places you need to get to (especially the hotel) and transport directions and details. Don't rely on a screen as batteries fail and connection gets lost.
Airport food is extremely expensive, if you can bring small snacks with you according to the flight rules, 100% do that. Stuff like popcorn/corn snacks and bottled water.
Charged phone/ipad/mp3 player and earphones are vital (and chargers). Wet wipes to freshen up, gum.
Have a nice time Anon!
