In a country like India where guests are likened to deities, it becomes your moral responsibility to properly care for your guests who come all the way to rejoice in your happiness and pray for your well being. In the exuberance of your Big Day, do not forget to incorporate the comfort and enjoyment of your guests, especially those with special needs.
Consulting with them in advance over their arrival plans is a good idea and you can also talk cordially and caringly about the arrangements that will need to be made. If you are feel the intended person may think that his or her presence will mean extra planning for you, then it would be better to approach the family members who can tell you specifically about their important needs.
The venue for the wedding and the hotel or place of accommodation should be easily accessible and the rooms allotted to them should have all the basic amenities with relative ease of use. Special arrangement should be made for those who use wheel chair or crutches for locomotion. They can very much use the same transportation facilities as you have arranged for your other guests but then do ascertain that others are sensitive & responsive towards them.
Don’t go out of your way to assist them in everything because this will only lead to embarrassment because you are making their situation very conspicuous. Treat them normally and made subtle arrangements for their comfort, for example save them the inconvenience of waiting in the dinner queue or keep help at hand in order to assist them.
It is also important that they enjoy your wedding but then it may not be possible for you to look after all their particularities. Still, ask one of your friends or family members to see from time to time that they are enjoying themselves or having a good time at your wedding.
