Jeana, go on your own. We took a water taxi, $6 per person both ways. The hotel is AWESOME, we spend 5 hours there, and I don't think we saw everything. We also took some food from the cruise ship with us in a bag back and had that for lunch, since the food there is really EXPENSIVE. We paid the $25 for the dig (we didn't pay for our son), but the guards at the entrance don't pay a lot of attention, and people tell me that they sneak in. It depends how honest you want to be. Just make sure you get a map (at the booth in the middle of the casino where you pay for the dig) and walk the whole property, there is something amazing at every corner, even at the edges of the property.
