Airport cabs from Barcelona port

[topnole]

We will be departing Symphony of the seas in Barcelona and heading straight to the airport as early as possible.  We are a family of 5 with 7, 5, and 2 year old.  Will it be a problem to find a can that can hold us?   Do all of the cabs take credit cards or will we possibly need Euros to pay.  We are coming over on the Transatlantic and going straight to Switzerland for the later part of our trip.  So no need for Euros otherwise.  
 

Also, booked business class seas on Swiss air.  Any idea how checkin will be -at the airport given we get to go through more expedited checkin as business class? 
 

Thanks for any info or advice

I don't have answers to your questions on Barcelona, but we have flown business class to Europe with our kids from the US (Houston, Texas) to the UK, Scotland, etc. and everything has always gone relatively smoothly. My kids are currently 8 and 10, but we have flown with them when they were younger...as young as a year.  You still have to go through security like normal unless you have TSA pre-check...although, TSA pre-check is only for the US so in returning you will have to still go through security regardless. (We have TSA pre-check and our kids get to go through with us under us.)  Still, it wasn't a problem.
