@m992572m - That sounds great, but when you get down to details, it's not so easy. If you're going away for longer than a weekend, what do you do about medication that needs to be refrigerated? What if you need to take medication that needs to be mixed with a lot of water, during times you're on a bus? What do you do if you're on a particular schedule at home that's good for your digestion, but you're with a group that eats at totally different times? How much fun is it to negotiate a strict diet, with tour operators, hotels, and small local restaurants .. especially if the tour operator arranges for everything to be prepared ahead of time, to save time when the group stops?
Nobody will take care of us, we have to tace care of ourselves. When and if we travel we have to keep everything in mind-if we are on medication is it strick times to have it etc.
In relation to the fringe-nearly every hotels has a little fridge. If you need water-you can always have a bottle with you wherever you go (this is what so many people do not to get hydrated), in relation to the food- even celiacs etc have a places that can enjoy it, and you can always contact the catering place and order something special-to your needs and requirements,usually these places are more that happy to help you.
People do solo traveling,people travel no matter what their age, people travel wiht kids and toddlers etc
As long as you feel ok...and if you want, there is always a way to solve any issues.
