How do I sterilise bottles in a hotel when I only have a microwave steriliser?

[cockle84]

Argh, we are going away to a hotel for the weekend tmw and I've just realised I don't know how I'm going to sterilise my baby's bottles as I only have a microwave steriliser.
What do I need in order to sterilse without using the microwave?
Thanks

Sterilising bags.

Some sterilising fluid and one of those spiky bottle brushes. I think thats what we used when we went away.

Those sterilising bags look good, how many bottles can you fit in each bag?
