How close am I to fit on all of the rides

I now weigh 240 lbs and I am 5'10" 1/2. How much more weight do I need to lose, especially on the Top Thrill Dragster and Wicked Twister. I also want to go on some of the older rides (Corkscrew, Magnum XL-200, Blue Streak, etc.)

Do you think I'll be able to fit on the rides at this weight? Or should I lose more???

First, I weigh 240 and am 5’11. I fit in all rides just fine, except WT, which is the only impulse I’ve been turned away from.
Second, are you a man or a woman? Men carry weight around the middle and women in their hips. You don’t have to say here, but keep in mind seatbelts fit around the hips.
Third, why stop now with over a month to go? You wanna gain it back? Keep reducing. It not only serves you well at the park but in every facet of life as well.

This winter I started to lose weight. I'm almost down 20lbs, but my starting weight was 224lbs. I never had any trouble except WT, I'll attempt it again this year. And I'll echo what RCMAC said, don't stop now and gain it back. You could probably easily lose 10 more lbs (depending on when your trip is, maybe more). And it will make life easier. I'm also trying to keep my weight down because my blood pressure is high and I'm on meds for it, so losing weight will probably help me with that issue as well. But when you decide enough weight is enough, don't just dive into eating everything like you did before. Just watch your servings.

Just a forewarning- Wicked Twister is INCREDIBLY unforgiving. It's the only coaster I can't ride (as of last year anyway). Some newer coasters are more accommodating though, including having a few special seats per train for heftier folks.
