We're going in April, and just wondering if we should make MGM a park we visit. We are going for 7 days, so we have the time, but don't have hoppers and wondering if there is enough to do for a whole day? We also made reservations at SCI-FI for dinner. Do you thing it is worth a TS credit (have the dining plan?) Our two children are 3 1/2 years old (twins). Thanks, Linda
