Wow you guys have done a lot of travelling over the last couple of years! How do you guys get so much time off work!? I can't get that much time off work unfortunately. One day I'm sure I will be able to get to those countries. We were planning on flying over to Europe in early June. Last time I was in Europe between June to August and I feel like all the people who told me that Europe is too busy in peak season over exaggerated. I really didn't find it that bad and the weather was perfect around that time.
I'm sure there are some really good providers for SIM cards over there. Research it up and you'll find something which is cheap and will give you good reception. The wifi in some places is a bit slow but it didn't really bother me.
A can't stress enough how handy a waterproof jacket is haha! I had one which could be rolled up into a small ball and had it down the bottom of my day bag. It came in handy quite a few times when I needed another layer to block some chilly breezes or when it randomly started to rain. It kept all my other clothes dry and saved me a lot of trouble. It was also handy when we were having snow fights in Lauterbrunnen!
I wasn't aware of the change to the 28 degree's MasterCard. I prefer to load the cards up with my own money but that is just a personal choice. I'm going to have to have to do some research about which card I want to take but will probably end up taking the Multi-Currency Cash Passport again as I had no troubles with it last time and it seems the fees are the same. There is a fee to put money onto your cash passport however if you go to flight centre and get the card through them they will wave all the loading up fees. I'm not sure if there is a fee to retrieve the money back off the card at the end. I had some money left over when I came back last time and just withdrew the money through ATM's here and wasn't charged anything.
Wow using the one suitcase between two of your for 8 weeks is quite ambitious haha. My partner and I are both taking 75L backpacks when we head over. That should give us both some spare space in case we buy some souvenirs and also makes them easier to carry around.
I only had a 2 hour stop over in Dubai so I'm not sure what the place has to offer. If I was staying there I would definitely want to check out the Burj Khalifa and go up to the viewing platform. That place is amazing. It would also be pretty interesting to check out the man made islands they have there.
