Greetings to Both of You!
Both Sam's and Costco are located on Orange Blossom Trail.
It might seem a bit out of the way, however we always seem to manage a trip to Costco while we're there.
From Sand Lake Road, head away from I-4 until you see the MOPAR building on the right near corner of the intersection. The cross street will be OBT (see street name above- it saves time). Make a right turn on OBT, and both Sam's and Costco will be on the right.
They are a decent distance away, Sam's will come up first.
We got lost the first time we attempted the trip, and had to call a few times to achieve success.
Both have gas stations, and both are usually the same price.
Great bakery items at Costco and Sam's- (I prefer Costco because the bakery does their own bagels). And just about anything else you could think of.
Hope this helps.....
