Haven't been since before covid so I don't know what's different now. But based on pre covid I'd say:
Book your times for the pool, breakfast and dinner asap, you used to be able to do so before arriving.
Ask for the free pop badges with every kids meal, they never seem to offer them unless you ask and my DC loved them. Any staff member would swap their pop badge with DC if they ask (might not be allowed now), also at one point shop staff had lego figures on their name badges and would swap those too so we'd take spare figures with us for that. Buy the bottomless drinks on park and put the pop badges on the lanyards.
Have a look at the rides with DC beforehand and find out which are their essentials, as you will not do all or even most in a day. Check where they are in relation to each other so you don't walk miles more than you need to.Without a qbot you might only do 4 or 5. If you can, get a qbot, book it in advance and you can collect from the shop in the hotel instead of on the park. Look up beforehand if there are rides which you can't qbot (there used to be, the boats and another popular one), do those first thing, before the queues are crazy. Often there will be a qbot queue, if so join and ask the staff member to bleep your reservation off while you queue, so you can get your next reservation on there counting down asap.
If you buy stuff in the shops you can have it delivered to the hotel instead of carrying it round with you.
Queues for food and drink on park are long and slow, so don't wait til DC are starving.
We used to do 3 or 4 days ( when it was buy one get one free) so it didn't get stressful trying to do everyone's wish list. We'd have one or two days with a qbot and make the most of it, then the other days play on the parks, water area etc and just do a few rides.
Its not exactly a relaxing break for adults, but the DC loved it!
