I've got a Losi Trail Trekker I'll pack along on family trips and vacations. Most all hotels, condos, etc have some nice rock laden flower beds or at least something to crawl around in. I can fit it and the remote into a small kid's shoe box.
If you're likely to do something like this the Losi Micro Rallys may not be out of the question. Something to zip around the parking lot and sidewalks with and ramping the handicap access curb. Been there and done that, too. I use a simple 2s charger for small helis/drones from eFlite. If the battery is under 400mAh, IIRC, it'll balance charge using the balance plug. Green/red LED makes it even easier.
But if you're going hiking or something real outdoorsy then you'd want to pack a 1/10 along. Or a 1/18 4x4 something.
Old Trekker with MicroCrawler chassis and a Bug body.
My Losi 1/24 chassis with a (I think) Mini Q body, SCT bumpers, and rally wheels.
I've got a Redcat Racing Sumo stadium truck. It's a 1/24 also and is AWD similar to the Losi. It's a lot cheaper and uses AA batteries. Surprisingly there's support for hop ups. I've got metal CVDs, metal diffs(from an HBX), a heat sink on the motor, and rewired it for 2s power using four 14500 3.7v batteries. It's taken some beating, but not as much as the Micro Cooper.
