buy now or wait?

just been looking at the exchange rate and today i see the best rate of 2.30 to the £
So should i buy now or wait a few more weeks to see if it rises anymore. We are gonna take OH nationwide card but i like to have a couple of hundred on us to get us started without having to panic about finding an atm.
Also should we exchange in resort to getter a better price?
Just keep thinking the more i get to the £ the cheaper the efes
