Pre-sterilsing bottles when going away?

[Gingerspice]

I'm going away for a few days. My LO only has 2 bottles of FF each day, the rest I BF for.
If possible I'd like not to take my Steriliser with me.
Am I right in thinking it'd be ok if I sterilise the bottles required (in this case 4) and then make them up. If I then don't open them until the feed is due, then this is an acceptable way to do this? Or will I have to take my steriliser with me?

The instructions on my steriliser say things need to be resterilised after 24 hours. Could you maybe bring some Milton tablets and just use a container of cold water?

ah, ok....I didn't really see the difference between having sterilised my own bottles and the ones you can buy.
I'll go with the milton tablets I think. Thanks
