I think we should take plenty of suncream. It’ll be really hot.
I think we should buy a book called See the World on $25 a Day. It’ll have some good ideas about where to go and where to stay.
I don’t think we should put too much in our backpacks. We won’t be able to carry it all.
I don’t think we should take anything valuable. We might lose it.
I think we should go to Australia first. I’ve got some friends there who’ll put us up.
I think we should go to Indonesia by boat. It’ll be cheaper than flying.
I don’t think we should wait too long before we go. I want to get started.
