I'm glad you found us, too, Gigi! Good for you for sticking to your guns! Too bad for them if they throw it back at you! You could just as easily throw back at them that they didn't originally invite you on the trip, and it was nerve to them turn around and ask you to be their taxi service! Or if you think that will just lead to a fight, then maybe just assert that you're not a taxi service. If they argue just keep restating it and change the topic.
Hope you do take that trip with your ds! Greece has such a great heritage - birthplace of democracy and all that - and so much beauty! And it's part of your and ds' history. So again, I hope you two go and enjoy!
