As I've mentioned before, we're making plans like crazy for New Zealand because it is the high season there in January-March, which means things get sold out easily.

We decided a while ago that we'd rent a campervan for the month that we're there. We were faced with a choice- a campervan with a toilet/shower or one without.  The difference in cost was about $1000 over a month, which is significant.

During our own research, we figured that we'd get one without a toilet to save money. Then, we talked to a travel agent who was able to get us a deal thanks to bulk buying power.  The deal we got made our estimates work (close enough) to go with the toileted version.  So, we've got that going for us for about $155 a day or $4300 for 28 days.

Now, the way we justify that much is this:  The campervan is both our transportation and our lodging.  Plus it is kitchened- so we can cook and eat on the road and limit out eating out.
