Med Tours - Preparing Payment

I really need to sort out what we will owe in both Euros and USD for our various tours and such while on our cruise in the Mediterranean. I'm ready to buy Euros from our bank but the cost hasn't dropped as much as I would have liked. The current rate is about $1.55 USD for 1 Euro. I don't know what our bank's current rate is - probably in the $1.65 USD range.

Here's the breakdown that I've figured based on an exchange rate of $1.55 USD per 1 Euro:

ROME: Rome in Limo transfer from FCO to Civitavecchia (6 passengers): 28.33 Euros per person + tip ($3 USD per person) = 66 Euros
Roma shuttle private transfer from Civitavecchia to FCO (2 passengers): 120 Euros + tip ($3 USD per person) = 130 Euros

SICILY: Celebrity tour already paid for. Tip ($3 USD per person) = 10 Euros

ATHENS: Spiros taxi service (8 passengers): 56.25 Euros per person + tip ($5 USD per person) = 128 Euros

EPHESUS: Ekol tours (6 passengers): $55 USD per person + $10 USD per person + tip ($5 USD per person) = $140 USD. Ekol will take USD or credit card and we also paid the $130 USD deposit for this tour for all 6 of us.

NAPLES: Italy Limousine service (6 passengers): 66.67 Euros per person + tip ($5 USD per person) = 148.83 Euros

Total: $140 USD + $482.83 Euros

I plan on picking up some envelopes at Staples today and labelling each envelope with the info for each tour and putting the amount that we need in them in Euros once we receive them from the bank. Hopefully this will make it very easy to keep things sorted out. Of course, we'll also need some pocket money but I'm thinking we'll need to use an ATM or 2 while we're out there. Looks like I need to order at least 500 Euros from the bank.
