Tips: Mumsnet is not the place to ask about the middle east. You will, as proven up thread, get some horrific, often uninformed, responses.
There are quite a few posters based out in the ME who talk much sense. And I don't know how some threads attract sense, and some turn into a bun fight.
I suggest finding a Facebook group that deals with expats. My favourite has just moved onto a paid platform, but there are general ones, and almost certainly Dubai specific ones. PM me if you want some specifics names to join.
I suggest thinking about what you wish to do with your house (if you have one) and furniture. Also start a big declutter. And devide if you want to ship stuff over, or pack your life into a couple of suitcases and start over. We airfreighted 30 boxes over - all the furniture is in the UK, in our house which is rented. We also have boxes in storage in the UK.
Do you gave kids?? If you don't need to be there in August for School, i strongly recomend delaying to September. August is brutal here, so I assume it will be in Dubai (I'm in Saudi).
Check the package VERY carefully. Packages are going down, cost of living is going up.
I think shopping the UAE is much easier than with me. I bring over bras, shoes (size 7 is hard to find), long legged trousers, shampoo and tampons in bulk. Also kids books, and (strangley) school trousers and jumpers. And sun hats for everyone. Usually bring sunscreen, but after some leads from @Orangebird69 have located some here (Thanks Orange).
Embrace the adventure.
