この公園はゴミだらけだからこどもを連れて来たくない。
This park is covered in garbage, so I don't want to bring my kids here.
Explanation
「だらけ」 follows a noun and means 'covered in' or 'full of': lots of something bad, dirty or messy, spread thickly over a surface or a whole space. The speaker feels disgust or complaint: 「泥だらけの靴」 (muddy shoes, covered in mud); 「傷だらけの体」 (a body covered in wounds); 「間違いだらけの宿題」 (homework full of mistakes). It is normally not used for good things.
Mixed up with
「だらけ」: a surface or area full of bad things (mud, rubbish, wounds, mistakes). 「まみれ」: body or surface smeared with sticky, powdery or liquid dirt (blood, sweat, mud, dust). 「ずくめ」: good things one after another, or all in one thing (「黒ずくめ」 all in black). 「っぽい」: has a tendency or character.
You cannot say 「×お金だらけ」 or 「×幸せだらけ」. It must be something bad or unclean.
