Further to my last reply, I spot-clean the Fitch each day, taking out the wet, scooping the poopy bits and replacing, and the entire lot (both trays) gets completely emptied and cleaned twice per week.
Using a hay rack will probably save you on hay, and most commercial cages come with racks. The advantage of these are 1) the hay is not piddled on, 2) you end up using less, 3) it keeps the hay out of the way so that you can fit an enrichment item in the cage.
However - piggies also enjoy having a large pile to rummage through, tunnel under, lie on and of course eat. A big pile of hay is, to my mind, an enrichment item. You end up using more this way, but he piggies do love it, and I've never found piddle to be a problem as I replenish the hay daily.

I'm a light sleeper though.

Some of them are loud squeakers, but they generally do this near and at veggie time, some cannot seem to walk without chuntering happily away to themselves, it's like their vocal cords are directly attached to their legs. Others are near-silent. You may find a quiet one turns into a vocal one as he/she gains confidence, or you may not. If your pair are have the sort of relationship that involves lot's of showing off and displaying at each other you may find them making noise with that too. They do sleep at night, but they also wake several times and have flurries of activity, so it really depends on whether you can get used to that and sleep through it or not. As I say, some of us have and do
