^I'm going to agree with this. The option is there for people to meet up at parks on all of these trips. I can't think of a trip that the itinerary wasn't posted to the forum before the trip started, so people could come meet up. So you could certainly come and hang out at the park and meet people or whatever. The only thing you're missing is (maybe) ERT and/or a meal, as these don't occur at every park. I personally like the fact that ERT is actually ERT, and not "wait in a line longer than during park hours" like any other event I've ever been to. As someone that has gone on two trips so far (and will be going to Japan next week), I'd hate to see this change. Having been to some ACE events/conventions and a couple of TPR trips, there is simply no comparison, and one of the big things that makes a TPR trip so much better is the limited number of people.
I must also say that while I'm all about seeing/experience new countries, if I'm paying to go on a coaster trip, I'm going on this trip to see parks and ride coasters. I don't want to make a stop at a cathedral (like ACE did) or anything else, as that's not what I signed up for. On both of the out of US trips so far, there have been some free times where people could go off and explore a nearby city or whatever, which is certainly a cool option. I sort of like keeping coaster trips and more "normal" trips separate.
I do believe that if you took the survey that was posted awhile back about future trips that there were some trips suggested that would be over a long weekend. I don't know if/when this type of trip will happen, but it should make it easier for people to go on a trip that cannot commit to over a week's time.
Bottom line, I think keeping the trips the way they are makes them easier logistically to plan and makes the perks for trip participants true perks. Just my dumb opinion, as always...
