We are selling seminars on our magento website. Every seminar has these 3 attributes 1. Hotels (select hotel or none from the available hotels.) 2. Select whether you are going alone or with partner. 3. Select date (from the list of available dates on which the seminar will happen) consider it like a single event with add ons as hotel and plus one (with your partner) which occurs for multiple dates. for example I host a seminar at a place in new york for multiple dates. (the same seminar happens for multiple dates). to create the seminar the flow should be - Enter seminar details (with some custom attributes) - Select the hotels from the list of available hotels - Create dates with number of slots available. (the dates which have passed will automatically go off.) the pricing will be like :- We have a base price of the seminar let's say 2000$ then depending upon whether you are going alone or with your partner and the hotel you select , it will add to the base price of the hotel. let's say Base price :- 2000 hotel one :- add 200 if you go alone / add 400 if you go with your partner hotel two :- Add 300 if you go alone / add 600 if you go with your partner . No hotel :- 2000 only the partner price is added only on the basis of hotel you selected. the webkul booking and reservation plugin offers this kind of feature but it is for single date only. it is also an option if we can extend this plugin to create events for multiple dates with seats.
