Yes, I do remember running to get lunch at drive throughs for the kids when getting the car either from the airport, after parks et.. I know one morning too we grabbed some muffins & doughnuts at the store to eat. One night we went down to International drive (short drive) and went to dinner at the Olive garden with the kids.
Also, we went to a couple of stores to buy some cheap trinkets for the kids. One was a soft Mickey blanket after my daughter was sick (we spent the whole day at the clinic waiting, pharmacy waiting etc..) and I bought her a bunch of gatoraide. sp? Also, we ran to get some more sunblock, beer

(on ice in the hotel).
When we go to Las Vegas we sometimes rent a car just when its the two of us. When we have brought our kids (gymnastics meet) we rented a car which our stroller broke so we cruised to wallmart to buy another one. It never fails with our kids that we have to go somewhere unexpected.
But sometimes when we travel getting taxi's can be cheaper. Depends on how much we have to change hotels/places and see other things. Sometimes it is cheaper than the RT transfers!
(quick story...we were in Vegas with some friends who wanted to use public transportation and buses for hire for everything...we were stuck at the airport for 6 hours previously, when we landed they wanted to go on a bus to get to the hotel. We smiled nicely and said OK...we wanted to pay extra for a taxi and get the heck to our hotel..needless to say,the bus wasn't full yet, so we sat there for over 45min. until the bus filled up...and it turns out the taxi would have been cheaper for the 5 of us)
I am just a huge advocate for my own transportation or quick taxi rides nearby!! Everyone is different
I also compare cost to renting and paying for parking as to how much realistically with tips for drivers it will be. This time I didn't because I knew we would need a car. I have to say that I was disappointed that you have to pay at the HRH for parking. But still for us it is more cost effective and flexible to get a car.
Can't wait for MAY 2nd! HRH club, cabana & fun!
