We wanted to book as a family of 4 with a cot through Tui/First Choice.
This hotel WILL NOT put a cot in a room for 4 they make you pay for 2 rooms or charge the full child cost for a child (ours would be 7-8 months) to put them in a bed. Plus as you need a larger room you are charged a supplement. So if you have a cot pay for 2 rooms and an under occupation charge (£70) or pay full price £250+ for an infant and a room supplement of £370 for needing a bigger room.
Riu/tui/first choice this should be made clear on your site!
