Please don't worry so much about "containing her." Eventually you will have to go through the stage of working with her to teach her to stay in her room (if not necessarily on her bed) at night. It must come, so now is just your time -- she decided it for you by climbing out of the crib. You will not be able to contain her at first; that's just the way it is, so prepare yourself for nights of returning her to her new bed over and over and over. That bed can be as simple as putting her crib mattress on the floor, which might be safer for her since she's a toss-and-turn sleeper who might wiggle right off a single bed or toddler sized bed.
It is tiring to make this transition, but it beats rushing her to the hospital with broken bones. I've posted this before but say it again here: My friend's 18-month old broke her arm the first time she climbed out of her crib; she fell from the top of the crib rail. If she had landed on her head or neck, she might have been killed. Put up the side of your child's crib and really look at the distance from that top, raised rail to the floor. That's a long way for a small child to fall, and falling on the wrong thing like the head could be fatal.
She will get up. I wouldn't discipline her harshly because she is too young still to understand why you're angry or disciplining her just for her getting up and down. In her mind, if she can move around, why shouldn't she? Put her to bed with the full routine and leave and tell her you will check on her in five minutes, then in five minutes, stick your head in the door - don't go all the way in -- look at her and say a very quiet good night. Come back in 10 minutes for a silent check, then 20 after that, etc. if she's still awake. She'll know you're there amid the changes to her room and routine. If this isn't for her and she pops right up and walks around, you 'll have to return her to bed EVERY time but do it silently -- don't engage her at all, talk to her, fuss at her. Just say "We stay in bed once it's bedtime" the first time only and walk her back to bed. She will take time but will learn that getting up does not get her any reaction, talk, or attention from you. It is tedious and tiring but is a phase that will pass if you can stay calm and not let bedtime be a fight. You might check out what supernanny Jo Frost has written about bedtime routine changes like leaving the crib.
But as for keeping her in the crib, crib tents, etc -- no point trying to corral her. Move on to this next transition.
