Hi Lisa,
Welcome to the forums firstly!
Secondly I can appreciate how you feel, I'm a chunky guy myself and I often panic going to new parks about what I can and can't get on.
Trying to translate womens sizes in mens sizes, you're not too far off myself, so heres my rough guide to things:
- Air - the worst part of the restraints about Air is the thigh of your leg, as thats the pinch point on the restraint. Its difficult to predict this one so try the seat at the entrance, theres usually a member of stafff who is happy to check for you at the entrance and release you from the seat.
- Nemesis - this is a chest one - I don't have any problems with it, however if you're really paranoid there are "big boy" (or girl :P) seats on the train, but I can't for the life remember which row and seat it is now. Usually row 5 seat 2 or 3, but I'm sure some Nemesis expert will be along to help with that one :P
- Ripsaw - not very forgiving, I don't bother with it as I've had little success with it
- Runaway Mine Train - the front half of each "carriage" is a little better for those with longer legs, otherwise should be OK
- Spinball Whizzer - again this one is hard to predict, and it has no test seat
Its the size of your leg thigh (i.e. top half of legs) and your stomach with this one - however, I've ALWAYS found helpful if you cross your legs over when you sit in the car - it should help to lower your thighs slightly to help the restraints close. It makes getting in and out take a few seconds longer, but its helped me get on the ride a lot. They have to get the small yellow arrow on the restraint arm within the yellow square on the restraint support down by your leg. So cross your feet over once you've stepped in the car!
- Oblivion - Oblivion again can be VERY unforgiving - it really depends on which car you get, I've noticed the "newer" looking restraints seem to have their latch point lower than the older discoloured restraint cars. Again theres a double-belted "Big boy" (or girl, sorry :P) seat available on the ride - when you get into the station, there should hopefully be someone on batching (once you've crossed the metal bridge) - ask them for the location of the big boy seat and they'll gladly help you with which one it is.
- Rita - I've never had any problems with the Intamin newer restraints at all, and I've never seen anyone refused from the ride myself, although that doesn't mean it doesnt happen. However there is a test seat at the entrance, try it out again
You should be fine with all the flat/spinney rides etc - the only ones I can't do is Ripsaw and Submission.
I know it's really awful to get turned away from a ride, but at the same time staff are usually really nice about it - its difficult to know what you can and can't ride until you've tried it once, so try not to wreck your day by not going on anything at all! You never know, they used to give me an 'exit' pass when I got refused so I could hop on something else instead :P
And always try the test seats - yeah you feel a complete tit trying it out, but it saves a lot of time queueing, and also that embarrasment (thats all in your mind remember!) if the restraint doesn't fit. Don't forget to ask them on Nemesis and Oblivion for the "big boy" seat locations if it will make you feel more comfortable too - you might think its really silly to ask them, but usually they are really understanding and if anything it helps them to keep the throughput up and delays down in dispatching
They will usually try and help you "fit" too if there are problems - just try and relax, take a deep breath in and then breathe out and they'll give your restraint a firm shove to try and get "one more click" usually needed to let the train go.
And finally - it happens all the time! Seriously! Don't think you're the only one in the whole day, theres probably been tens and tens of people that day already
Hope you have a great day, and keep up the diet efforts - it is worth it in the end, I'm on a strict diet to go to Florida now
lol
Joely
but my hips are what I'm worried about. My trouser size is a ladies 20/22 and I dont think I will fit into the seats on Spinball wizzard or Air. Does anyone know the seat/hip size for these?
