After reading this topic yesterday, I have booked with Travel Republic for the first time for our first visit of the year, in early April. We normally have a private taxi, which costs about £60 return (we have always used the same place, so they give us an excellent price
).
Thought we'd try the shuttle bus as there are only 3 of us travelling together. Total cost was less than £27 return. As we have four visits this year, this is a good saving, moreso when only me and hubby are flying (less than £18 return).
Will give it a try on everyone else's recommendation. By the way, Travel Republic use A2B Transfers according to the receipt.
