We used Blacklane in Portugal with great success. Carey was twice the price for us also. .so I decided to use Blacklane. Plan on using the, again in the future.
Only problem it was a larger group so I needed a bigger bus and we had to prepay. Would not take a credit card so had to do,PayPal. Then there was a discrepancy with the exchange rate that caused issues and many emails. I think they normally take credit cards so this may not be an issue in your situation. But the payment was a pain.
