Yes that is a possibility, but more so if it were a long term deal. For a five year deal whilst apparently building a new stadium i would suggest access is better reflected for CCFC in the monthly rent
As to the other posters comments - Do you not think that just as CCFC will want to minimise costs and maximise income that Wasps would not want to do the same. As they own the rights to incomes and the lease at the ground the level of charges or access will be set by Wasps in their favour not CCFC's. The choice CCFC have is to accept, try to negotiate or walk away. Wasps are certainly not going to just give parts of it away, and as i understand it see the current deal as undervalue, whether or not CCFC or its fans see differently. CCFC are in a weak position to make demands
If Wasps see the current deal as undervalue, and are looking to increase their own turnover & importantly net profit then it isnt too much of a leap to think a price hike for any new deal is on the cards is it? The alternative is a ground share somewhere outside of the City. Not saying it is best for CCFC just that realistically that is what i see happening.
Just another thought but just as Wasps have been saying for over a year no deal unless no legals, then Wasps have had over a year to prepare for CCFC not being there. Their Plan A might be having CCFC there but what is Plan B if CCFC not there
