Leaving in 3 days -- Forgot to Make Money Transfer Plans

So I'm a procrastinating idiot, and I'm first realizing that having money to indulge in the Vegas cash games will actually require me to withdraw/transfer some money. Anyway, I'm leaving Thursday morning, which leaves me with the following few questions...

1) If I play to bring ~$3-5K, is it even necessary to plan any workaround to simply carrying the cash on the plane with me? Should I wire? Traveller's checks?

2) If I do need to wire, is there more lead time required than just 3 days in order to have the money waiting for me? Can wires be done over the phone?

3) Worst case scenario, if I don't take any money with me, will I be able to withdraw $3-$5K from a casino ATM machine without getting charged up to wazoo?

Help me salvage my vacation.
