What about portable DVD players with headphones? I also plan on taking my laptop and don't want it checked, nor do I want it out on display as a means to watch DVDs. I also have a DSLR outfit that is going along.
It would appear that I jujst want too much, doesn't it?
I don't think you want to much. Unless you're expecting the flight attendants to carry it all through the airport for you...then you're expecting too much.
Gate checking the seat is going to be the best way to minimize the nonsense that might happen to the seat. You will still carry that seat through the airport...so by the time you get there you might just carry it on anyway. But anyway, you get it through the airport, ask for a gatecheck tag for the carseat if you want it to be gate checked, and for the stroller too.
Then as you board, you will leave the carseat (and you can put it in a bag made for travel by the way...I bought one from Target) and the stroller at the end of the ramp, just before you enter the plane. The employees will walk up the stairs from the tarmac, take the gatechecked stuff, and put it on the plane. When you reach your destination, they will take the stuff off and put it back in the same place on the destination ramp for you.
Yes there are opportunities for them to be rude to your stuff. But not as many as if you check it at the ticket counter and wait for it to come crashing down the carousel.
As for laptop and DVD player...bring 'em in a carryon! As long as you have packed well and given yourself enough time, it won't be a problem. We have a couple backpacks with padded spots for laptops, then other pockets for other electronics. I bought a Fül brand backpack for DH at Costco about 6 months ago, tons of pockets, well within carryon sizes even for the puddle jumpers he's been on in Canada recently. Carries his laptop, several electronic devices (he's a product tester for kindle), mp3 player, etc etc etc.
After you board, putting the carseat(s) in the proper place (needs to be at the window...and if you take both seats on, I think the second can be in the middle, so two seats in a row), getting settled in...take the DVD player and a DVD out, put the needed things in the seatback pocket in front of you, along with anything else you might need. Stow those away, then stow away your bag that held those (which by that time can probably fit under the seat), and then relax.
If you're going to experiment with earplanes, get headphones NOT earbuds. And even headphones are going to be weird with the earplanes in...DS insists it's fine, but then, he tends to lose an earplane when he does that because it wiggles around when he jostles the headphone.
And don't listen to the movie without the headphones, of course.
