Well, we just decided last night to go to Disney after school gets out (I have a timeshare week that's about to expire and I was able to get us reservation at Horizons by Marriott - I've been wanting to go there). That takes up one week. Shortly after we get back, the kids start summer school for the month of July. That's half day. If I get my tax return soon, we'll join a pool. The beginning of August we're going on a cruise with my cousins, dad, aunt and uncle. If possible after that, the kids may do a week long camp. DD wants horseback riding and DS wants gymnastics. But, we'll see. I'm kind of playing it by ear.
DD has done the all-day, traditional day camp thing, but never really liked it. DS is pretty much open to anything.
