Hi,
Firstly congrats
Secondly, it'd be a shame if you couldn't go on a lovely honeymoon..
How are you levels now? was your recent DKA a one off or are you having recurring DKA?
I don't think it's stupid at all, going abroad can be a challenge, with heat and different foods, different routine.
The heat will usually make you more sensitive to insulin, so you would have to adjust a little over the first few days until you get used to how your body reacts to a climate change.
If your DKA was a one off and you have good levels, i don't see why you should cancel. If you do decide to go make sure you research what medical care is available near where your staying, pharmacies, emegency Doc appointments and local hospitals.
Also make sure you have good insurance, make sure the insurers cover you for EVERYTHING, some insurers will cover you despite you having diabetes, but if something diabetes related happens, it's a different story, paying a little extra to peace of mind is a little sacrifice in my eyes, there have been some great threads on this so if you search the site there will be some suggestions on good places to look.
If your sensitive to food you can take some things of your own, my friend once took heinz baked beans so she could have beans on toast if she didnt like anything (very picky eater!)
If your DKA is recurring and aren't getting particularly good levels, then maybe it would be a good idea to cancel and re-arrange, you want to enjoy your honeymoon and have a good time, especially in a place like morocco!
Maybe you could have a hotel weekend away in the UK somewhere, there are lovely hotels in lovely quiet pretty areas all over the UK. Spend quality time with eachother as newly weds and have an abroad honeymoon later on when you are more confident in going abroad.
Whatever you decide to do i have you have a lovely wedding and a nice honeymoon
