I would also look into a taxi. Particularly if you are a family of four, it might be cheaper than a Mears shuttle. Mears has taxis also and could probably give you a cost for taxi fare to and from your destinations. I don't have their number offhand, but if you search "mears transportation" you should get their website and then their phone number.
