I'll contact the hotel if they have a pre-paid laundromat. I dread the idea of going to the laundromat and wait for the nappies to washed and dried
Yup definitely flushable liners

I will also take lots of pockets and quick dry aios with me, and fitteds for night. It's only 3 days so it's probably not worth doing the laundry

I'll pop some detergent in a zip lock bag just in case anyway, since they're mostly pockets so it should be easy to wash in the shower
Still not sure if I should just use plastic bags or get a bummis bag
