I've never been in a taxi in my life. I've researched through the Mears site approximately how much fares will cost to get from CBR to theme parks outside of Disney & a quick trip to Walmart, however, I don't know how much it is customary to tip the driver. There would be no luggage involved, just us. Is it a certain percentage of the fare? Is it based on how many people(4)? Is it just a estimated figure? Also, for a quick trip to Walmart for supplies, is it out of line to ask the driver to wait or do I just arrange a pick up time with him when he drops me off? Thank you! I am learning so much from these forums.
