Which is a very good thing, since I found a site (holidaytaxis.com) and have booked transfers to and from the airport for a total of £90! So I've saved over £200 there!
I now have nothing left to pay on my card, and have $1650 now. So I'm very happy right now. Even if I don't add any more, that's enough for us, although I will be adding more and will be getting money once out there, so things should be fine!
And I don't have the added stress worrying about the car hire or credit cards etc. I just need to sort out what I need to pack, what paperwork I'll need and how I'm going to cope for 2 weeks away from Ben!
