I must question the reasoning behind doing so many pushups & crunches.  I feel a person would be better off doing a full body strength training regimen, just 2-3x a week, in place of all that daily stuff.  Your body will be able to recover better from the full body routine, better than it would from doing just pushups/crunches on an endless mission.  Sorry to be so blunt, but it sounds like your program is lacking some direction and goals for a good solid strategy-based solution to your needs.

Other advantages of doing a full body workout is that you'll help your entire body work as one, in strengthening your core, legs & upper body, enabling you to gain better fitness benefits overall.  Full body workouts can be done with a set of adjustable dumbbells & a stability ball.  Focus on exercises that target your quads, hamstrings, chest, back, shoulders, and midsection. 

A quick example of exercises for those body parts would be:

Dumbbell Squats

Dumbbell Lunges

Dumbbell Chest Press on Stability Ball

Dumbbell Bent Over Row (for lats/biceps)

Dumbbell Side Raises or Shoulder Press

Ab Crunches on a stability ball

Back Extensions or Hip Bridge on stability ball

This would give your total body a good start in strengthening it up overall. 

Just some suggestions,

It sounds to me like you have added some very good exercises to your regimen. Since this is an opinion board, my opinion is, stick to using your own body weight wherever possible. One, if you do that, your gym is always with you. You can do a simple pushup/situp (I actually prefer leglifts and crunches as they are easier on my back) deep squat workout  anywhere, so you can't say "Well, the hotel didn't have a gym".

Also, you can do it anytime. Roll out of bed and hit the floor. Drop during your lunch hour or before bedtime.

Finally, If you do the exercises the correct way, slow and controlled without bouncing or swinging, you will be less apt to hurt yourself. We have all seen the guys in the weight room swinging the huge weights or bouncing the bench bar off their chest, basically inviting muscle pulls or ligament or tendon damage.

You want stamina? Do them in sets one right after the other without out a rest break. I would recommend adding a few exercises such as deep squats using only your body weight. Do a few sets of 50 of that, and you will feel it. If you get bored with the simple pushup, change it up. Do dive bombers, or diamond pushups. I have recently added a set of dive bombers and do my pushups with one hand on a soccer ball, to give added work to the rotator cuff muscles that stabilize the shoulder.

If you have been able to add those exercises to your regimen, and you do them in good form, slowly and with control, you have the workout you need.
